I am trying to:
enable the new relationships model in the toolset -> relationships page
Link to a page where the issue can be seen:
only on the admin page
I expected to see:
The relationships dialog
Instead, I got:
A progress bar... forever? I have waited on the page for around 1 hour now, nothing seems to happen.
however, on other pages I am able to navigate and see my custom post types, etc. I can also navigate the site either as an admin or I can see the site's coming soon page when I log off of my account.
I would gladly upload an image but I get an HTTP error when trying to upload my 97KB jpg file.
I can't really tell what happened, I found out later that the Divi builder was giving me timeout errors at this point, I disabled all plugins... and the last one I disabled (caldera forms) seemed to be the culprit — The site worked before with toolset unregistered + caldera forms — anyway, after googling I found this solution to the WPMU support forum:
Add these lines to the .htaccess file
<IfModule mod_substitute.c>
SubstituteMaxLineLength 15M
</IfModule>
I was then able to re-enable all the plugins I needed + the relationships showed up as expected + the Divi builder did not timeout anymore.
I leaves me with the feeling that the site may be shaky :-/
