Hello not been on here for a while.
Our website has recently been updated at long last to Joomla 1.5.25 from Joomla 1.8. I had struggled for a while getting our host to add sound files and managed to sort it with ALLvideo. After our host changed over, it was removed and the reason was 'it wasn't compatable'. I now see fro Foti that a version for 1.5 is now available. Does this mean it is also ok for 1.5.25? Also I am looking to add an extension for site content protection and found this plugin

extensions.joomla.org/extensions/access-a-security/site-access/content-protection/10217

would this be ok in our new version or do you recommend another. I just want to reduce the copy/pasting and disable right click with the option for it to remain possible for the admin end. Finally as a super administrator on our website am I allowed to add these plugins my self?
I look forward to reading your reply. Many thanks.
