Dev Server: Art Library - stuck on "Loading recent Uploads".

I have two campaigns on the Dev Server. In ether, when I click on the Art Library tab I see just the header, a spinning wheel and "Loading recent Uploads". It never changes. I have let it sit there for over an hour. If I enter something in the search bar, the "Loading recent Uploads" message goes away and I get three new messages, Spinning wheels and "Searching your Library", "Searching Purchases", and "Searching the Web". These stay there forever.&nbsp; It has been like this for a very long time on my Dev Server campaigns (weeks or months - I rarely truly need to do anything with the art library on the dev machine, so I have no idea how long). My production server campaign is OK.&nbsp; I see that others have reported identical things 8 or 9 months ago,&nbsp; <a href="https://app.roll20.net/forum/post/6204975/new-uploads-never-finishes-loading-when-trying-to-filter" rel="nofollow">https://app.roll20.net/forum/post/6204975/new-uploads-never-finishes-loading-when-trying-to-filter</a> <a href="https://app.roll20.net/forum/post/6120097/loading-recent-uploads-spinning-forever" rel="nofollow">https://app.roll20.net/forum/post/6120097/loading-recent-uploads-spinning-forever</a> but both threads end with them saying the problem just went away a day after the devs started looking into it, with no clue as to what the problem actually was.&nbsp; I am using: Windows 10. Chrome Version 70.0.3538.110 (Official Build) (64-bit) I have cleared the browser history with no effect.&nbsp; Here is the console log, from when I entered the VTT, but it contains nothing I saw of interest, except for possibly ... app.roll20dev.net/:1 Access to XMLHttpRequest at '<a href="https://app.roll20.net/image_library/validatefolderstructure/" rel="nofollow">https://app.roll20.net/image_library/validatefolderstructure/</a>' from origin '<a href="https://app.roll20dev.net" rel="nofollow">https://app.roll20dev.net</a>' has been blocked by CORS policy: No 'Access-Control-Allow-Origin' header is present on the requested resource. app.roll20dev.net/:1 Access to XMLHttpRequest at '<a href="https://app.roll20.net/image_library/fetchorphanassets/false/1" rel="nofollow">https://app.roll20.net/image_library/fetchorphanassets/false/1</a>' from origin '<a href="https://app.roll20dev.net" rel="nofollow">https://app.roll20dev.net</a>' has been blocked by CORS policy: No 'Access-Control-Allow-Origin' header is present on the requested resource. It did not change at all when I switched to the Art Library tab, so I posit that the message was there the entire time, and switching chat window tabs just allowed me to see it.&nbsp; jquery.migrate.js:20 JQMIGRATE: Logging is active app.js?1543361116:370 70 app.js?1543361116:371 TOUCH SUPPORTED: false app.js?1543361116:371 USING WEBGL ACCELERATION... app.js?1543361116:371 WEBGL STARTUP SUCCESS app.js?1543361116:373 Custom Sheet Translation app.js?1543361116:365 select app.js?1543361116:365 Switch mode to select app.js?1543361116:385 Initializing new dice engine with randomness... app.js?1543361116:385 Using random entropy app.js?1543361116:388 Compiling sheet... app.js?1543361116:388 Found webworker script jquery-1.9.1.js:6469 The specified value "(@{Adjust-Attacks-Total-CC}-@{condition-Darkness})" is not a valid number.

I said, it has been doing this for quite some time and would like it fixed if possible.&nbsp; Thanks.

Thanks for the complete bug report Chris, I'll flag the devs for attention.

Thank you Drespar,&nbsp; The problem is ongoing.&nbsp; Per your suggestion, I created a new campaign on the Dev server, When I went to the Art Library, it did not immediately have the spinning wheel and "Loading recent uploads". However as soon as I clicked "My Library", I got it and it never went away. When I asked it to do a search, I got the three spinning wheels and searching library, purchases and web messages that never go away. So it looks like the new campaign is exactly like the existing ones.&nbsp; I had previously looked at my extensions and did not see any that looked at all problematic. However, I have just gone in and disabled every single one, and entering the campaign gives the exact same result. I am using windows defender and it shows no issues.&nbsp;

OK, yes, that seems to be giving a big clue.&nbsp; As per my original message, there is no additional console log activity when I change tabs.&nbsp; When I enter the search term Horse, however, I get... Access to XMLHttpRequest at '<a href="https://app.roll20.net/image_library/usersearch" rel="nofollow">https://app.roll20.net/image_library/usersearch</a>' from origin '<a href="https://app.roll20dev.net" rel="nofollow">https://app.roll20dev.net</a>' has been blocked by CORS policy: No 'Access-Control-Allow-Origin' header is present on the requested resource. app.roll20dev.net/:1 Access to XMLHttpRequest at '<a href="https://app.roll20.net/image_library/search_marketplace/tokens/horse" rel="nofollow">https://app.roll20.net/image_library/search_marketplace/tokens/horse</a>' from origin '<a href="https://app.roll20dev.net" rel="nofollow">https://app.roll20dev.net</a>' has been blocked by CORS policy: No 'Access-Control-Allow-Origin' header is present on the requested resource. app.roll20dev.net/:1 Access to XMLHttpRequest at '<a href="https://app.roll20.net/image_library/websearch/tokens/horse/1" rel="nofollow">https://app.roll20.net/image_library/websearch/tokens/horse/1</a>' from origin '<a href="https://app.roll20dev.net" rel="nofollow">https://app.roll20dev.net</a>' has been blocked by CORS policy: No 'Access-Control-Allow-Origin' header is present on the requested resource. &nbsp;Note that this is slightly different from the messages I flagged in my original post as being slightly suspicious.&nbsp; app.roll20dev.net/:1 Access to XMLHttpRequest at '<a href="https://app.roll20.net/image_library/validatefolderstructure/" rel="nofollow">https://app.roll20.net/image_library/validatefolderstructure/</a>' from origin '<a href="https://app.roll20dev.net" rel="nofollow">https://app.roll20dev.net</a>' has been blocked by CORS policy: No 'Access-Control-Allow-Origin' header is present on the requested resource. app.roll20dev.net/:1 Access to XMLHttpRequest at '<a href="https://app.roll20.net/image_library/fetchorphanassets/false/1" rel="nofollow">https://app.roll20.net/image_library/fetchorphanassets/false/1</a>' from origin '<a href="https://app.roll20dev.net" rel="nofollow">https://app.roll20dev.net</a>' has been blocked by CORS policy: No 'Access-Control-Allow-Origin' header is present on the requested resource. The top block of this post is for doing a search for Horse tokens.&nbsp; The 2nd block of this post is what it did while loading the VTT (and resulted in the spinning wheel and "loading recent uploads".&nbsp; When I do the same thing on the Production server I get the following message 34 times (and see lots of horse tokens). app.roll20.net/:1 Mixed Content: The page at '<a href="https://app.roll20.net/editor/" rel="nofollow">https://app.roll20.net/editor/</a>' was loaded over HTTPS, but requested an insecure image '<a href="http://t3.gstatic.com/images?q=tbn:ANd9GcSN6psPXczljLxc5QzseCaz_jxvKa7e1OetOVyRipKed13sv2nh_VuA5cC6" rel="nofollow">http://t3.gstatic.com/images?q=tbn:ANd9GcSN6psPXczljLxc5QzseCaz_jxvKa7e1OetOVyRipKed13sv2nh_VuA5cC6</a>'. This content should also be served over HTTPS. &nbsp;&nbsp; So now we just have to figure out what&nbsp; CORS policy&nbsp; &nbsp;is, and how come I am the only one not sending&nbsp;&nbsp; &nbsp;'Access-Control-Allow-Origin' header. Unfortunately, it leaves me clueless, but I am hoping it means something to you.&nbsp;

This is still happening and I would love to see it fixed.&nbsp;
