Need Help Resolving Several Technical Issues with Prestashop Website

  • Answered
Prestashop website was moved from a Windows virtual server (hosted by HostGator) to the current Linux server (with InMotion Hosting).

An InMotion Hosting technical support team-member referred us to Community Support for help with the following issues.


Issue 1:
Login to Prestashop:
Backend > catalog > products > edit (tabs on right) > Update a Product/Save = Generates error: An error occurred while updating an object. product ()

Issue 2:
Pop Up appears in same location after 10 seconds:

Tab : ModuleSimplewatermark (200)
A server error occurred while loading the tabs: some tabs could not be loaded.
Please try again by refreshing the page.
If you are still encountering this problem, please check your server logs or contact your hosting provider for assistance.

Specific module is not installed, is no longer available through Prestashop addons marketplace and cannot be found in site files that were migrated. They may be located in the line below that is referencing Windows:

Now in the file it is referencing a Windows line:
define('_PS_DIRECTORY_', '/C:/Program Files (x86)/Parallels/Plesk/var/apspackages/apsA0D4.tmp.zipf94a9599-1bfa-a13e-70/cache/scripts/');

Example of a file generated on our server:
define('_DB_SERVER_', 'localhost');
define('_DB_NAME_', 'bsahqo5_pres645');
define('_DB_USER_', 'bsahqo5_pres645');
define('_DB_PASSWD_', '42S.75RLP!');
define('_DB_PREFIX_', 'ps_');
define('_MYSQL_ENGINE_', 'InnoDB');
define('_PS_CACHING_SYSTEM_', 'CacheMemcache');
define('_PS_CACHE_ENABLED_', '0');
define('_COOKIE_KEY_', 'vgtdrfidunwtounqokxdw1xnafmfq38k2y6jbjx4dfma3h6ddirzogye');
define('_COOKIE_IV_', 'ektzkwpm');
define('_PS_CREATION_DATE_', '2015-09-11');
if (!defined('_PS_VERSION_'))
define('_PS_VERSION_', '');
define('_RIJNDAEL_KEY_', 'N9PfCfea8ZBuuYSwoxNr6fQD2nCGJn4c');
define('_RIJNDAEL_IV_', 'ZQmEYHRwk94xHfA9sverOA==');

That directory line is not generated. I removed the line but was still unable to save an edit to the product.

Hello Jimmy, I would suggest loading your PrestaShop installation from the previous host and export your products and settings via the dashboard. Then you will need install PrestaShop and re-import your products and settings. This is due to the windows settings within your configuration, which is why you are most likely having most of these errors. Best Regards, TJ Edens
