Host suggesting problem with .htaccess
Installation and Configuration
Update: Checked the tpl file - no javascript (!) . Uploaded a new .htaccess file -no change.
Followed the instructions here to increase the memory allowance (
https://blog.arvixe.com/setting-custom-php-ini-files-for-your-website/). Created a check file at ourtownstory.co.uk/check.php and the new php.ini file is being used.
Currently running another offline integrity check to see where that gets me. There's something in the back of my mind that is niggling that's related to the parked domain thing. I am now fairly sure the server is working right, but I don't understand the 502 error. And until the Integrity Check on Sunday night, it seemed like a CSS issue - it seemed to be then that it keeled over terminally.
Update again: Offline repair ultimately generated 504 error - took too long to respond
