Description of my issue:
Please refer to previous ticket number #19885 which was handled successfully by Davide Tampellini.
In brief - ticket #19885 described a problem with Akeeba that resulted in a blank page being displayed when trying to make backups (and other Akeeba Backup functions). It was resolved by removing bad data/files from FOF (I don't fully understand but it cured the problem).
To be honest - I don't know if my current problem concerns Akeeba or not. But please read on !
The problem I now have is that I can't install extensions. I am trying to install JCE editor. I'm fairly sure that this is NOT a permissions problem since the zip extension uploads to the tmp directory and unpacks into an install directory and from there the relevant directories and files are created for the component.
BUT - it seems the installer can't write to the database since there are no entries in _assets _components etc. Installation process stopped with server error 500 after about 2 minutes - which might be db timeout I guess - but why ?
The database user has full permissions and I can create content without problem.
I usually use the MySql interface but have also tried MySqli without success.
Why might Akeeba be involved ? Because at one stage I also had Admin Tools Pro installed and as I recall, Admin Tools overrides the standard Joomla Extension Manager. I uninstalled Admin Tools because I had started to experience problems with upgrading to new versions. I just did not have the time to resolve these problems, so uninstalled - but I recall that the uninstall may have been somewhat messy.
So, I am wondering if there could be some residue of the Admin Tools Installer that is hanging about and causing the standard Joomla Extension Manager to fail ?
Is this likely or possible ?
Alternatively, if I were to re-install Admin Tools (would it install ?) is it likely that this would resolve my problem. Does basic Admin Tools include the extension installer or does that require the Pro version ?
