 * Hi [@hcetin032](https://wordpress.org/support/users/hcetin032/)
 * I hope you’re well today!
 * We’d need to know the exact error the site gives to be able to find out why it
   happens and how to fix that. I’m not aware of any generic/general errors that
   could cause that and usually it’s a matter of site or server configuration/resources
   or some unexpected conflicts.
 * So to find out about specific error, you can do as follows:
 * 1. enable WordPress debugging by adding following lines to the “wp-config.php”
   file of the site, above “/* That’s all, stop editing */” line:
 *     ```
       define( 'WP_DEBUG', true );
       define( 'WP_DEBUG_DISPLAY', false );
       define( 'WP_DEBUG_LOG', true );
       ```
   
 * 2. once they are there, try enabling the plugin (newest release) on site again;
   it will fail again but this time you should find out a file called “debug.log”
   on server in the “/wp-content” folder; if you look into that file you should 
   see some errors listed there, especially fatal errror(s) – so let us know what
   exactly those errors say.
 * As for revert to older version, since you have access to the site you can simply
   do as follows:
 * 1. download older version of the plugin from this page (form at the bottom):
 * [https://wordpress.org/plugins/forminator/advanced/](https://wordpress.org/plugins/forminator/advanced/)
 * 2. go to “Plugins -> Add new” page and use “Upload” option there to install plugin
   from downloaded zip file
 * 3. during the process you’ll be asked if you want to replace existing files with
   uploaded ones – so confirm replacement and that’s it; plugin will be reverted
   to older version (though if it’s inactive, you will need to activate it again
   to use it).
 * Kind regards,
    Adam
