Due to the fact that MochaHost cannot offer support for third party application specific issues/errors, we highly recommend that you visit the application's vendor support page. These often will contain the exact fix that you need or a guide on how to resolve your specific issue.
Here are some of the more popular application support pages:
Wordpress: https://wordpress.org/support/
Joomla: https://forum.joomla.org/
Drupal: https://www.drupal.org/support
Magento: https://experienceleague.adobe.com/docs/commerce.html
Zen Cart: https://www.zen-cart.com/forum.php
PrestaShop: https://www.prestashop.com/forums/
DNN: https://dnncommunity.org/forums
If your application is not listed above you can look online for the support page in your specific case.
