Hello,
The plugin is installed like that plugins/content/jw_allvideos
But in plugin management joomla is looking for plugins/content/_jw_allvideos
the language files are missing.
I have duplicated the folder to have one with each name in order to the plugin to works but its a strange behaviour

MP3 player dont works on phone or tablet
I use plugin version 4.5 with joomla 2.5.17

Please try to uninstall completely the AllVideos plugin (both jw_allvideos and _jw_allvideos) and try to make a fresh installation. If the problem persists post me again.

Hello
I have desintalled many times but i need to have the folder plugin named  _jw_allvideos otherwise i get an error manifest xml not found.
I had not these problems before, except for the plugin not working on phone and tablet which is the reason i upgraded to 4.5.

This is nothing I have heard before. Is it possible to sent me access to your backend via PM in order to check it out?

Hellol,
I have retryed to desinstall the plugin and make a fresh installation, now its good. :)
Last problem, the pugin dont work on android or ios, any idea?

Could you be a little more specific about that?
You don't see the video at all, you see it but its not responsive, etc.
