Hello, I'm trying to update to Joomla 3.8, but my current version of vData (2.9.12) causes the update to fail with the "Error: 0 Call to undefined method JAdminCssMenu::addChild()" issue.
I have confirmed this by uninstalling vData and running the update on my staging server.
It would seem the fix for this is in the latest vData update, but now I can't install that either.
When I try, using the "Upload Package File" option, I get this error:
Code:
JInstaller: :Install: File already exists /mnt/data/vhosts/mysite.com/httpdocs/components/com_vdata/index.html
Component Update: Failed to copy site files.
Package Update: There was an error installing an extension: com_vdata.zip
My permissions appear to be correct per Joomla standards. 644 on files and 755 on directories.
I could just uninstall and the re-install after upgrading (which I've confirmed works), but I have quite a few import and export profiles that I don't want to lose. As far as I can tell I can't export those separately from the extension.
Is there anything else I should try to get this to work?
