On a page with many sections, I can't copy or delete sections. No problem on pages with less sections. Debug Info:
|message||expected expression, got '<'|
Can be both the server and the browser, see this post on stackoverflow
Could also be sth. different though
Should be fixed with this commit.
Seems to work well here.
Please test and report any issues. It's only an early hotfix.
FYI: In fact we did't use GET but POST to save the section data. So it wasn't an URL string length issue but we actually exceeded max_input_vars on the server side.
