As the title mentions - I can't upgrade any module at all.
I have ensure the correct PHP version on the server, I have trawled internet searches and tried all suggestions without success. I can see others with the same issue with no solution. Tearing my hair out.
I have tried both upgrading from the BO, and uploading new modules and neither work.
When upgrading, the error message says: Cannot upgrade module "any module". Unfortunately, the module did not return additional details.
Server logs show: AH01071: Got error 'PHP message: PHP Warning: Declaration of BWDisplay::setTemplate($template) should be compatible with FrontControllerCore::setTemplate($template, $params = Array, $locale = NULL) in /var/www/vhosts/gamer-tech.co.uk/httpdocs/modules/affinityitems/backward_compatibility/Display.php on line 30\n', referer: https://gamer-tech.co.uk/dan/index.php/improve/modules/manage?_token=YEuIIfnrztuIfiCu88EsI2_d0nfvPPYlw7LtbkbLQbI
With debug mode on the BO, the error message when an update fails changes to: Exception thrown by module "any module" on upgrade. Warning: Declaration of BWDisplay::setTemplate($template) should be compatible with FrontControllerCore::setTemplate($template, $params = Array, $locale = NULL)
Desperate for help on this
