Hi there!

Thanks for contacting us.

If your SPPB verion is the latest one, then you can ignore the upgrade notice. The SP Page Builder latest versions are compatible with Joomla 4, no worries.

The following blog post may help:

Have a nice day!

I updated SPPB to the latest version, but I still see the message: The following plugins could cause problems during the upgrade: System - SP PageBuilder JoomShaper.com
System - SP Page Builder Pro Updater

What to do?

I updated PB to the latest version, ignored the warnings and started the update. As a result, I see the message: The server returned a "500 - Whoops, looks like something went wrong." The site admin panel is also unavailable.

Hi,

Sorry to hear that. Did you check and follow the blog, please?

More specifically, were all the components Joomla 4 compatible before starting Joomla update? And did you keep a full backup of your site?

Best Regards

Yes, a backup has been made. I found the reason - before the migration, you need to rename the .htaccess file. And after migration, return the name. In this case, my migration was successful
