I tried the above text page on the remote server and receive this message'
Fatal error: require(): Failed opening required 'Welcome.php' (include_path='.:/usr/lib/php7.4') in /homepages/37/d415519235/htdocs/boatsforsalenow/webassist/email/WA_Email.php on line 314
Earlier I was trying to find the email I installed but could not see this, I could only see a new empty form "Create Email Message".I am attaching the files below.
I hope these are the correct files.
Thanks for your help
