Hello Admin

Please clear your Joomla cache and Browser's cache and then check. If possible, then check with a different browser.

Best regards

If I may....

so you had this error message only in one of many pages?

It was a large page, I mean with many rows, addons inside or what something else special on that page?

I have clear cache, and locks, and used different browser and still blank pages. This happens on all pages. Reverted to version 3.8.8 and it works fine. Installing 4.0.1 and blank pages.

So keep 3.8.8 by now, and relax for next few weeks, no rush.

I am still trying to get pagebuilder to work. I can not edit any pages. I have updated joomla to version 4 but when I attempt to edit the home page in page builder I get the error, Sorry, there was a problem we could not recover from.

The server returned a "500 - Whoops, looks like something went wrong."

I've paid for a subscription and expect to be able keep this product up to date. I was able to edit pages in Joomla 3.10.11 and pagebuilder pro 3.8.8 but have never been able to edit pages under 4.0. The privious post to just use 3.8.8 by Frank is not an option.
