500 error on Payments page after moving Prestashop to another domain

[Vee.K727]

Hi, I've recently moved my website to another domain and I started having this issue with Back Office > Payment > Preference page. When I click on it, I get HTTP 500 error. I enabled the debug mode and got this error

Compile Error: PrestaShop\PrestaShop\Adapter\Module\Module::instanciateLegacyModule(): Failed opening required '/home/olddomain/public_html/presta/modules/ps_wirepayment/ps_wirepayment.php' (include_path='/home/newdomain/public_html/presta/vendor/pear/pear_exception:/home/newdomain/public_html/presta/vendor/pear/console_getopt:/home/newdomain/public_html/presta/vendor/pear/pear-core-minimal/src:/home/newdomain/public_html/presta/vendor/pear/archive_tar:.:/usr/share/php')

It seems this page is still looking for the old location. How do I update this?

PS - To move the site, I cleaned the cache, updated domain in ps_configuration and ps_shop_url, changed database details in app/config/parameters.php, regenerated htaccess file from back office.

Try searching on the disk and in the database for "olddomain".

@musicmaster THanks a lot mate. That solved the problem. I found the olddomain in files in var/cache/ directory. I deleted the folders and Prestashop created new ones. The page opens now. Weirdly, no tutorial on the internet says to delete this folder.
