I rescently installed Ordasoft's Book Library component for my site. After installing it and navigating to the component in the 'Extend' menu I get the following error:
Fatal error: Cannot redeclare class JToolBar in /home/XXXXX/public_html/libraries/joomla/html/toolbar.php on line 302
Ordasoft checked out my site and reported the its an error in the template. I changed back to the default Joomla admin template and their component worked fine.
Any reason MissionControl would return this error? I would really like to solve this as I much prefer using the MissionControl template.
Thanks for the quick reply. The problem has actually fixed itself. I simply changed back to the default template, loaded the extension once and then changed the admin template back to MissionControl and it now works every time.
Cheers
Andrew
ps. BookLibrary can be downloaded for free if it helps.
