My forum is now offline and can't be used, it's stuck on "The site is currently being upgraded. Please check back later."

Fatal error: Illegal length modifier specified 'f' in s[np]printf call in .../src/vendor/league/flysystem/src/Adapter/Local.php on line 199

Any resolution suggestions?

The only instances reported of this error have been due to the PHP version/build.

Which version is running on the server?

Try upgrading to the latest 7.4 if possible.

Thank you, this resolved the problem


I was on php 7.2 previously though, bit disappointing that this happened.
