Control Panel not loading relationship or file fields
Development and Programming
Some of my channels are not loading pickers for relationship fields or file fields. When I noticed they had stopped working, I upgraded from 4.2.1 to 4.3.8 then to 5.2.0 in the hope that this would fix it, but to no avail.
In the control panel when looking at an entry in one channel, for example, the relationship field now just shows a loading bar when it previously displayed entries from another channel with selectable radio buttons.
When I enter the browser’s error console, it reports the following:
[Error] Failed to load resource: the server responded with a status of 403 () (index.php, line 0)
https://www.domain.com/system/index.php?S=60451489f00988546e96e5578f73b2e3&D=cp&C=javascript&M=combo_load&plugin=ui.touch.punch&file=cp/global_end,cp/files/picker,fields/textarea/cp,fields/relationship/mutable_relationship,fields/relationship/relationship,fields/file/cp,fields/file/file_field_drag_and_drop,fields/file/concurrency_queue,fields/file/file_upload_progress_table,fields/file/drag_and_drop_upload,fields/grid/file_grid,cp/date_picker&v=1552322086[Obviously I have made the domain name and system folder name generic for this public post.]
The same error shows twice because on this page because this particular channel entry page has fields for a relationship picker and a file picker, both of which just display loading bars.
If it’s any help, the server is running PHP 7.0.33.
Any ideas anyone?
UPDATE: FIXED Thanks to Robin and, particularly, Kevin for the feedback. I contacted my host, the excellent Zen, armed with the idea that it might be a mod_security issue. Tim at Zen couldn’t spot any logs indicating that mod_security was being triggered by my IP address but asked that I leave the issue with him to explore further. The next morning I found that the issue was fixed. I don’t know yet what the issue was, but it was clearly something in the shared server environment rather than the ExpressionEngine installation. Thanks again everyone!
2nd UPDATE: The reason my IP address wasn’t showing in the logs was because we go through Cloudflare, so it seems that it was a mod_security issue. Thanks again for everyone’s help!
If you go to that url directly, does it load for you with the js or do you get the 403? And it’s only on some channels but not others?
With a 403 status code, you likely have mod_security enabled and need to relax the rule regarding log query strings.
I’m having a similar issue updating channel entries and believe it’s tied to mod_security with a shared bluehost account.
Every time i try to modify a channel field that links to a picture file, I get an infinite looping ‘loading…’ bar which never goes away. The console suggests a 406 error with the drag and drop file utility. I suppose I’m going to have to call bluehost and see if they can do anything about it, but it’s very very troublesome.
I have just installed the 5.3.0 version of EE, with the Default Site option, and am running into this problem. I am also on BlueHost shared, and have just gotten off support with them. They have turned off mod_security for my site, but I’m still having the same issue.
