We had the same problem, but only with German installation, on the same domain, probably the Siteground Security Plugin or the docx plugin was to blame. After both were deactivated, the WP Editor loaded again.

Problem solved.

– Clean unfamiliar Theme Panel injected code (example – https://i.imgur.com/4q70kCv.png);
I´ve found this code in the custom code, removed it, but the redirection is still on the page.

We never used the opt-in builder (using thrive leads for leads) but however, if this opt-in-plugin is activated or not activated, the error code from my first post in this thread is still again here, if i update to a newer version than 11.5.1
Also i have installed the standard pack and bug is still here, if i don´t downgrade to 11.5.1 or earlier.

There is also no opt-in plugin from tagdiv and after visual problems (without update or a logical reason) from the Big Grid Flex 4 Tagdiv Editor i made a update to the newest version and the bug is back …

Now i have a bug in the older verfsion on the startpage or an bug on the tag div editor with the newest version.

As I said, even if all plugins except tagdiv were uninstalled, the error message came up. Only after a downgrade to an older Newspaper version the problem was fixed (no error).

After downgrade to 11.5.1 it works, so the bug comes from the early and newest version

And now the startpage has this strange sourcecode again.

Additional note: Exists Blog articles can no longer be edited in Tagdiv composer, no error message is displayed, but the page continues to load endlessly (empty)

A blank new post is possible to edit with tagdiv composer with NO Error and NO hanging loading problem
After this test now the startpage

After testing this, tagdiv composer now loads dead on start page with no error message and no real composer content

There is a window said: DID YOU DISABLE ANY TAGDIV PLUGINS?
Close
We’ve got some errors at loading API files. It could happen because of a disabled TagDiv plugin!
OK
No i don´t have disabled TagDiv Plugin and i can still edit some tagdiv elements of the startpage, but the error is strange!

Yes i have it like in your screenshot.

Thank you.

It simply does not respond to the -400 specification of the button remains under the image.
