Joomla! version: 2.5.8
PHP version: 5.3.3-7+squeeze14
MySQL version: 5.1.66-0+squeeze1
Host: Linode
Admin Tools version: 2.4.4
Description of my issue:
Unable to perform Joomla update. The error message is "Error: AJAX Loading Error:"
I've deleted the tmp directory as suggested with no effect.
I've also reinstalled admin tools without effect
I have several other sites on the same hoas where everthing works as expected.
I suspect a permissions problem but everything looks ok in this regards.
Thanks for you help
