Urgent! JEM 2.2.3+ Backend Problem creating new venue!

[jojo12]

I can reproduce this issue (from 2 others) in forefox in Backend on a clean joomla 3.9.14 on php 7.3.11 with protostar template and JEM 2.2.3. On JEM 2.3.0 prerelease too! I don't know since when this comes. (Because the use of creating new venues is not so needed, it is possible, that it is not yet found earlier.) In backend I create a new venue, I insert a name, then I go to image and choose an image on my harddisk. Then I click "upload", I get the notification, that the upload is ok. But immediately the editvenue window closes and there's no new venue saved. (meanwhile the solution is: Before choosing and uploading an image, you first have to save the new venue, after you can upload an image!) BUT: THIS ist not a solution! URGENT! EDIT: the same problem, when you want to create a new event with an image!

@jojo12 I cannot re-create the issue in Chrome or Edge on J! 3.9.15-rc + JEM 2.3.0-beta3.2 in either front and back end. Can you confirm it happens in Chrome / Edge on your machine?

[jojo12]

@depebo: I tried with chrome: there's no such problem. in events, categories and venues. Only in firefox! Will test in other browsers. EDIT: In Edge it works fine.

I don't know, if you just did find a solution. With Webconsole in firefox developer I found the following: (see image). there seems to be a deprecated thing (in joomla 3 too) Is it possible, it has to do with jquery and an old jquery-migrate? But I found too, that they planned to update jquery-migrate for joomla 4. But joomla 4 is too late. Is it possible that JEM uses joomlas jquery which is deprecated? And only firefox is strict with deprecated? # Infos SyntaxError_image.pdf

[depebo]

only happens on 64 bit version of Firefox

[jojo12]

should firefox know this difference?
