I am getting the following error message
QuoteFatalErrorException in CustomerLoginForm.php
Error: Class CustomerLoginForm contains 2 abstract methods and must therefore be declared abstract or implement the remaining methods (AbstractFormCore::getTemplateVariables, FormInterface::submit)
I checked the CustomerLoginForm.php file and no changes have been made to it. I verified against a backup copy I have of the code from last year.
I did get an email from my hosting provider that my PHP version (v7.1) is out of date 11 days after the incident happened. I think that might be related to my issue, but want to get more information first.
The only changes I recall making were installing 2 new modules, but my website was working properly even with the new modules installed and configured. I've since uninstalled the modules & went into debug mode with the various settings. I attempted to upgrade but my website was displaying many error messages.
PS v1.7.3.1
I have a new theme that I want to use that is compatible with PS v1.7.6.2. I am eventually going to upgrade but am not sure if upgrading to the newest version PS will also update this PHP file.
Any suggestions on how I should go about fixing this?
