Joomla! version: 2.5.3 (just updated from 2.5.2)
PHP version: 5.2.17
MySQL version: 5.1.61-community-log
Host: Bluehost
Admin Tools version: 2.2.1 pro
Description of my issue:
I was installing Admin Tools Pro for the first time. I had just backed-up the site as well. Following the instructions on the Admin Tools guide, I performed an upgrade of joomla since there was an alert in the Admin Panel reminding that a new version of Joomal was available. Then I got the following warning:
"Refresh Manifest Cache failed: Extension is not currently installed."
See image attached.
Questions (they are a couple, but all related):
1) What was that ? I "reloaded the info from the server", as instructed, and the message disappeared. Is it all OK now ?
2) Just in case, does upgrading Joomla require disabling plugins ? I receive such a warning if I try to update via my webhost.
3) Before purchasing Akeeba pro today I had an issue with Xmap, which prevented access to my backend. So I restored my site (thanks to Akeeba !) to the pre-Xmap version. Are these incompatible? If yes, Akeeba has its own Site Tree. What extension is Akeeba friendly ?
4) Finally, I am new here, but why are so many tickets labeled pending when the issue, in many cases, seems to be concluded ?
