good morning,
I install allvideo on joomla 3 / purity III. the installation was fine but when I want to open the module, I get the error message :
! ) Strict standards: Declaration of JWElement::render() should be compatible with JFormField::render($layoutId, $data = Array) in C:\wamp\www\odedweiss\plugins\content\jw_allvideos \jw_allvideos\includes\elements\base.php on line 17
could you please help me to sort it out ?

Thank you

Hello burette,

This is not an error (or even a notice) message.
A Strict standards notice (which will be fixed in the next version) will not affect your site's functionality.

In order to get rid of the issue simply disable error reporting from your site's global configuration since core Joomla! components throw similar messages.

thank you very much.
One more question : I don't manage to resize the pictures either using the plugin fonction nor in the article or menu. Here is for example a line I put in a module (only 1 line in this module) then called in an article.. .It just take the full article width. Do you know what is wrong there ? thank you very much.

If you are using the responsive template then the video will be automatically stretched to full (available) width.
