500 internal server error when saving settings

It sounds like a PHP error of some sort. I’ll have a look.

I haven’t found any errors. However, there may be something specific to your setup or a setting that you are trying to save that is a factor. Can enable debugging and post any error messages below?

Sure – here is the error log

That’s perfect. Thank you.

I’ve released an update. Please try the new version.

Still no joy mate ??

New errors – even just saving without pchsnginf any values.

I think I’m on php 7 if that helps ?

Did you see this new error mate? ^^^

It looks like you are running a version of PHP prior to 5.4. I’ve modified the code to support earlier version and it should work for you now.

We are running PHP 7 ! Not an old version

The only issue I could find was with a language construct not available in an earlier release of PHP. However, the latest changes are a little more robust. Let me know if it works for you.

Bingo ! Saves fine now: thank you
