Blank media popup after upgrade to 7.x-2.0 or later

Hi, thanks for the reply. All those modules are up to date (I don't have multiform). After trying to upload an image, I get about 15 log entries, all 404s, for various images on my site, along the lines of:

TYPE	page not found
DATE	Friday, 12 May 2017 - 4:32pm
USER	[my admin user]
LOCATION	http://www.mysite.org/sites/default/files/styles/square_thumbnail/public/040217%20025_lr.jpg?itok=u6VSEXyx
REFERRER	http://www.mysite.org/media/browser?render=media-popup&types=&activePlugins=&id=media_wysiwyg&plugins=undefined
MESSAGE	sites/default/files/styles/square_thumbnail/public/040217 025_lr.jpg
SEVERITY	warning
HOSTNAME	46.208.75.6

Is that likely to be related? This wasn't the image I was trying to upload into the content, but as I say there are lots of entries for different images that don't seem to have anything to do with what I was doing yet do mention media_wysiwyg.

Thanks Joseph, I've just tried that (I'm using TinyMCE) but it hasn't made any difference.

Hi Joseph, many thanks for all the replies. I have updated to 7.x-2.2 and cleared caches without any change to the issue. I confirm that the image style square_thumbnail exists. Log messages after just testing adding images into content now say:

Notice: Undefined index: media in _token_field_info() (line 1334 of /home/mysite/public_html/sites/all/modules/token/token.tokens.inc).

Notice: Undefined index: module in FieldInfo->prepareInstanceDisplay() (line 628 of /home/mysite/public_html/modules/field/field.info.class.inc).

I don't know how to get more info for you on the undefined index issue.

I've also got:

User warning: The following module is missing from the file system: flag_terms. For information about how to fix this, see the documentation page. in _drupal_trigger_error_with_delayed_logging() (line 1128 of /home/mysite/public_html/includes/bootstrap.inc).

I've had the latter error for ages (it comes up whenever I update any modules). The Flag Terms module is unsupported so I deleted it from my site some time ago. I doubt that error is related to the media one but should I reinstall Flag Terms anyway or is there some better way of getting rid of the error? Do I just manually delete the Flag Term module's table via phpMyAdmin?

Re Varnish, thanks, I don't think I have that installed on my server but will check.

UPDATE: I confirm Varnish is not installed on my server.

Hi, I did have core 7.53 installed but just updated to 7.54 - no difference :-(

Token is up to date. Still getting this though:

Notice: Undefined index: media in _token_field_info() (line 1334 of /home/mysite/public_html/sites/all/modules/token/token.tokens.inc).

After updating core I got:

Notice: Undefined index: module in FieldInfo->prepareInstanceDisplay() (line 628 of /home/mysite/public_html/modules/field/field.info.class.inc).
Notice: Undefined index: module in FieldInfo->prepareInstanceDisplay() (line 628 of /home/mysite/public_html/modules/field/field.info.class.inc).

I have several other odd log messages now, still including the plugins=undefined one, but mostly about missing modules and themes, which aren't missing. Maybe my site has got corrupted somewhere. Should I try repairing the database via cPanel or something?

EDIT: I'm not expecting help on my general Drupal install etc - just thought I should repeat the messages I'm getting.

Thanks for the tip about the Missing Module Fixer - I didn't know it existed but I installed it and that message has gone away.

Not sure I can give you a copy of my entire database for security reasons.

I've set up a completely new, vanilla site on the same server with 7.54 core and the most up to date versions of Media, Token and a few other essential contrib modules, done some basic configuration and can confirm that I have no problem uploading images there whether in a field or via the media browser in the wysiwyg.

I've also just updated Media on another site of mine (also on the same server) and have no problem there either. Token isn't even up to date on there, and core is two versions behind (7.52). I get the missing square_thumbnail issue on this site, so that when I upload an image via the image field I get a broken image placeholder in the submit form, and get a 404 in the logs for sites/files/styles/square_thumbnail/public/myimage.jpg, but that's all - it doesn't affect the display of the image in the content or corrupt the whole content upload process (no 500 error) in the way that I'm getting on the first site.

Media browser settings incidentally are exactly the same on all three sites.

I guess the site where I'm reporting these problems is just messed up :'-( All I can say is there isn't any custom code on there, but there are a hell of a lot of contrib modules. I suppose the only answer is to create a fresh install and use Migrate to recreate the site and hope for the best...

Thanks for all your help Joseph.

Thanks, will do :)

Joseph, thanks for the tip - I reviewed my file entity permissions and there were quite a lot unticked in fact, but even after ticking all of them for my role and clearing cache I still got the same problem.

My issue is about the media browser, but note I can't upload any images at all, even through a separate custom image file field. When submitting my page with a file "uploaded" via that field I get the 500 error. I'm not sure if that was clear. Does this help identify the source of the problem?

Hi again... I haven't done a complete check against all the modules installed on my site but I have tried turning a few "likely" ones off and testing and none made any difference. I did think because of the 500 error that it could be something to do with directory permissions, i.e. the files weren't getting saved to my server properly, but I have checked and they are all actually being saved in sites/default/files. Not sure if that helps.

@joseph, re #32, I've now updated to 7.x-2.3 and still getting "plugins undefined" in the logs:

location: http://www.mysite.com/admin_menu/flush-cache?token=_5231SDKIkaesXnvD080tIyrigmttwVbwIFm4MxSRwM&destination=node/add/article

referrer: http://www.mysite.com/media/browser?render=media-popup&types=&activePlugins=&id=media_wysiwyg&plugins=undefined

re #34, yes I tried that while still using 7.x-2.2 and it didn't solve the issue.
