Response form returning parse error 
Autore: Donald M.I have a site with a response form which has started showing the following error when the user tries to use it to send a message:
Parse error: syntax error, unexpected ':', expecting ';' or '{' in /freeola/users/3/7/sr2621473/htdocs/res/x5engine.php on line 5475
My ISP is set to PHP 7.4. It was changed up to this fairly recently after a previous issue and this new issue may have happened at around the same time but I can't be sure, however ----
---- I note that in a previous question it was stated that the problem must lie with the ISP, however I have three other sites with the same ISP, also containing response forms, and they are still working normally.
The website is www.furniturerenewservice.co.uk
I have attached a copy of the X5engine.php file referred to above.
Check out if it works when you go back to php 7.3 or change up to php 8.0.

As it turns out, my ISP had given me incorrect information-they were actually on PHP 7.3. A switch to PHP 7.4 solved the problem.
Doesn't explain why the form worked for a couple of years and then suddenly stopped working,
