Updating your extensions using Regular Labs Extension Manager fails. Error message: Installation failed.
I tried downgrading to the stable version of RLEM, to no avail.
This was ok before your server went down the other day.
There have been some changes that affect all my extensions. So if you have 1 development version installed, you should update all Regular Labs extensions to the developer versions. Not advised on your live site!
You can set the Regular Labs Extension Manager to also look for developer versions in the configuration settings. So you can install them directly from there.
This is on my development site, I never install betas on the live site. And yes, RLEM is set to install dev versions. 😁
But I see now where the error is, it's in the individual extensions.
If I download e.g. Cache Cleaner (latest dev version) from your site and try to install using the normal Joomla installer I get this error:
There was an error uploading this file to the server.
Unable to find install package
So the failure isn't in RLEM, but in some of the extension install files.
