I know maybe isn't from zara theme. But this forum is better than Official Osclass forum so i will post this here. (Sorry Admin)
I have problem with uninstaling one plugin.
Here is the problem

Thank you ! 

I found how to do it but now when im trying to install the update i get this error
"Notice: Use of undefined constant MCRYPT_RIJNDAEL_256 - assumed 'MCRYPT_RIJNDAEL_256' in /var/www/vhosts/lannonce.eu/httpdocs/oc-content/plugins/payment_pro/functions.php on line 14 Notice: Use of undefined constant MCRYPT_MODE_ECB - assumed 'MCRYPT_MODE_ECB' in /var/www/vhosts/lannonce.eu/httpdocs/oc-content/plugins/payment_pro/functions.php on line 15 Fatal error: Call to undefined function mcrypt_decrypt() in /var/www/vhosts/lannonce.eu/httpdocs/oc-content/plugins/payment_pro/functions.php on line 16"

Only first error is important. Issue is with Payment Pro plugin, but it might be problem with your hosting as well. You should contact plugin author, he should guide you what is issue with this function.

I resolve the problem by changing my php version from 5.3 to 5.6.
Thank you.
One extra question, i have zara version 1.0.7. How can i recive the update?

@mixradu
PHP 5.3 is very old...
Login to your account and download theme, everytime latest version is linked.
