I tried to create a UDT .. assume there was some error in it as when I saved it the page went blank - and now I cant access the site at all, i just get blank white page whether looking at the front end or the admin area... help?!

Ive tried deleting the cache folders contents but that didnt work... where are the UDTs stored? Maybe i can edit manually...

Nothing new showing in web logs either when i try and load the sites, but here are the last entries for access/errors:

[Tue Jul 05 09:15:02 2022] [error] [client 31.53.112.96:0] AH01071: Got error 'PHP message: PHP Parse error: syntax error, unexpected ''\r' (T_ENCAPSED_AND_WHITESPACE) in /home/sites/21b/e/ec69e75dd5/public_html/lib/classes/class.usertagoperations.inc.php(306) : eval()'d code on line 1\n'

[05/Jul/2022:09:14:53 +0100] "POST /admin/editusertag.php HTTP/1.1" 500 - "http://xyz-com/" "Mozilla/5.0 (Macintosh; Intel Mac OS X 10_15_7) AppleWebKit/605.1.15 (KHTML, like Gecko) Version/15.1 Safari/605.1.15"

ok - I actually managed to sort this by finding the UDT entry in the database through phpMyAdmin and deleting it

The brings about the question why this is happening though? If i make a mistake with a UDT surely it shouldnt bring the whole site down - I havent even called the UDT on any pages

I suspect it may be something specific to your server PHP environment. I use UDTs all the time and, of course, make mistakes all the time. I work in many different server environments and never had the whole site down on account of an error on a UDT and not with one not being used in any page. Maybe some sort of firewall or something? Although I don't think it accounts for a site down, backend and frontend. I've seen ModSecurity break on UDT save on some occasions but never like that.
On a positive note, glad you found your way around it and recover it.
