My guess is that the problem is an incompatibility between the ancient forum software and a recent browser update. I don't think we changed anything in the forum software recently, but browser updates are routine.
It's 100% server side, not client side.
While it only started causing internal server errors recently, if you look back at mikeh's old posts, prior to when he had to start posting the word 'test' and then editing, every one with a funny character is now messed up - even ones he (or anyone else) posted a long time ago - e.g.:
https://www.bridgeba...ost__p__1055237
All his curly-apostrophes, which he always uses instead of plain apostrophes, are now showing as , as well as other special characters like dashes. They 100% did not appear like this when I originally read the posts, and it's a classic symptom of a server-side character encoding issue. Someone has messed up the database charset.
You can use this to narrow down exactly when this was done -
this post at around midday on December 10, EST was his latest one which went through successfully (but then became messed up in the database, as did all the ones prior to that). His next post on December 13 mentioned he had been having problems posting.
So the database was messed up somewhere between those dates - would suggest checking the logs for what was done in that range. If it wasn't an upgrade, it's a very common mistake when transferring old databases from one location to another - perhaps there was a server migration somewhere behind the scenes.
Another example from someone else in 2019.. posts prior to last month are now simply littered with them.
