In my latest version 3 Joomla site, I just updated two of your excellent extensions, Sliders and Tabs and now all 9 extensions and the Extension Manager have disappeared. The Libraries/Regular Labs directory only has one file in it now, the script.install.php
I have restored backups of the Libraries/Regular Labs directory and the MySQL database and the many red error messages have disappeared so the website seems to be working ok now. The only issue I can see at the moment is the Extension Manager has a lot of blanks in it - the blue buttons are all blank and there is no written indication of which extensions are installed, however, all 9 Uninstall Xs are there.
How do I fix this, and make sure this doesn't happen again when I update the extensions, please?
That worked, Peter, thank you for such a speedy response, however Tabs and Sliders show as 8.2.2 (up to date) in the Extension Manager, yet on the Joomla Update page they show as 8.2.0. I am afraid of reinstalling Tabs and Sliders in case it deletes the Libraries/Regular Labs directory contents again. Please would you look into the cause of this, Peter?
