Solved: Blank pages caused by syntax error in language.php file
I suddenly found many of my pages appearing as completely blank on what had been a fully functioning site.
This included all pages of a certain language.
It was tracked down to a single syntax error in a language.php file.
I had added a translation and only deleted one of the backslashes at the beginnin gof the line - the remaining single backslash caused the error (which wasn't being reported).
If you've suddenly got blank pages, and have been editing a language file, check for syntax errors.
Hope this saves someone the headache I had sometime 😉
