Now I did an Akeeba backup and updated a plug-in. Then I started the installation. However, it stopped shortly after 90% after an Ajaax error was reported. Of course I didn't remember the error message! What a brain!!!
I don't remember which version of three I had installed before, but it was displayed as the latest version. However, I do remember that there was an intermediate triple version that I knowingly didn't install in this case - so let's assume that I didn't install it.
I'd like to do a restore, but it's not possible via the backend, as the broken Joomla lists all the menus at the top, obscuring much of the backend. If I make the font extremely large, I can navigate to the individual menu items in the backend, but I only get error messages such as:
Code: Select all
An error has occurred!
0 Call to undefined method InstallerHelper::getExtensionGroupes()
Code: Select all
An error has occurred!
500 Table 'd028f607.jomkas_workflow_associations' doesn't exist
Thank you and best regards
