HTTP 500 error

[PP123]

HI, 

yesterday I disabled a module and following this I got a HTTP 500 error on my site. I have looked at the logs and found the error code: 

AH01071: Got error 'PHP message: PHP Fatal error: Class ProductListingFrontController contains 3 abstract methods and must therefore be declared abstract or implement the remaining methods (ProductListingFrontControllerCore::getListingLabel, ProductListingFrontControllerCore::getProductSearchQuery, ProductListingFrontControllerCore::getDefaultProductSearchProvider) in /var/www/vhosts/postpack.co.uk/httpdocs/override/classes/controller/ProductListingFrontController.php on line 0'

Any help would be appreciated. 

Thanks

Most likely the overrides made by the module were not properly removed. You could go into the module, see what overrides it does on install, then check and delete what's left in /override/classes/controller/ProductListingFrontController.php.
