XF 1.5 Any help for Datawriter.php error please


New member
hi all,

Ive got my forum up and running. Everything is good and people can post /login etc.

The problem I have is that if you do anything that means it should throw an error message such as " you must enter a title to the post" it just crashes to this

So this is created if you dont put data in a field and press submit.

EAccelerator for PHP [More Info ↑] Caches compiled PHP pages ONLY when running in a persistent (DSO/FCGI
It's very possible that IonCube and Eaccelerator are causing problems. We've commonly seen problems with PHP 5.4 and APC, so Eaccelerator may have the same issues. If possible, I'd probably recommend upgrading to PHP 5.6 or newer, but that may not be viable.

Restarting your PHP server (the web server or PHP-FPM server) may also help, but it can be temporary.
