After install the latest version fo your ARK editor this message appears and the waamp server crashes during a few seconds. I think the problem would be the incompatibility of versions. How can i fix the problem??

Hi arturo.para,

It seems  like you don't have the right version of the  JComponentHelper class file : libraries/cms/component/helper.php.

The isInstalled method was introduced to the JComponentHelper class in Joomla 3.4. So your version should have it.

I would suggest getting a full install of Joomla 3.5 and replacing the file from your install with the one in that package.

Kindest Regards,

Hi Andrew,

Thank you for your answer, it works perfectly. Now I have another problem to fix. Joomla does not let me to save articles. Should I reinstall the version to 3.5? I think there is a huge incompatibility problem.
