Thank you both for your advice. I contacted my web host after my previous post. It turns out to be one of those irritating co-incidences. The server was indeed upgraded with a hardened php, together with Suhosin. It was done at pretty much the same time as I upgraded my board.
They've made the suggested amendments server-side and everything seems back to normal.
Please feel free to delete or move - problem solved.
I hasten to point out that the problems I had were not related to the vB update, and I probably should have waited for my webhost to respond before posting here.
My probs were due to my webhost hardening php and adding Suhosin to the server. This was done on the same day I upgraded my site.
Adjustments were carried our server-side, and I've had no further problems with 3.7.4
Since upgrading to 3.7.4 I can no longer save changes to my CSS - eg, whenever I make a change to a style and click Save CSS I'm presented with the following message:
Required variables have gone missing and execution can not continue. Please try again.
This error can sometimes occur as a result of Suhosin / Hardened PHP being installed on your server. If you know that you have Suhosin running and you have access to the PHP configuration, try increasing the value of the following variables:
