Hi, I'm experiencing the following problem.
When I am editing a SP Pagebuilder page in back-end mode (which works) and then want to switch to front-end editor mode I receive a 403 error.
I see the following logging in the blocked request log:
Suspicious Core Parameter https://gus-productions.com/index.php?option=com_sppagebuilder&view=form&id=2&layout=edit-iframe&Itemid=191&lang=*
lang=* (in light grey)
In the .htaccess config in admintools I already added
administrator/components/com_sppagebuilder
components/com_sppagebuilder
as per https://www.joomshaper.com/documentation/sp-page-builder/sp-page-builder-4/troubleshooting advise.
But no succes.
Any idea what to do now?
