i try to install again the stable version but i have again the error on istall "could not find install package" so i did it again throug install directory

but the error is there again

please advise what to do

I don't see how CB could cause this. We don't act on onDisplay Joomla event. Disable 3rd party Joomla system and content plugins 1 by 1 to see if issue resolves. Ensure you've a Joomla editor enable and available to your user as that event is used by Joomla editor extensions.

Be sure you are not unpacking the zip file. It's a Joomla package that is installed all at once. Simple select for upload and installation. If that's not working you may need to increase your PHP upload limit through PHP.ini (contact your host for help in doing this).

Hallo there

Yes indeed i had unpacked and not upload it at once. I rolled back through a backup and it is solved now

Thank you
