Hi @haietza ,

How did you get this error? I just fixed the PHP 7 compatibility issues from the other issue you posted yesterday and I'm wondering if this will still occur for you. I tested exporting (with and without anonymizing) an entire forum and a single discussion and it all worked fine for me.

If you get a chance, please let me know how you got this so I can reproduce and fix. Thanks for the feedback!

Hi @chadmazilly ,

These errors appeared in the php server logs, just from exporting a forum in the Moodle course. I just downloaded the latest code from the master branch and re-tested and these warnings are still appearing in the logs.

Thanks for your speedy response!

Ok got it. Did the export actually work for you?

[haietza]

Yes - the export worked fine. Just noticed the warnings in the logs.

Ok great. I'll leave the issue open but fixing the warnings from coming through may be a big task. Looks like that MPDF PHP dependency being used is a huge library, developed over 5 years ago in an older version of PHP. I'll keep you posted here.

Sounds good - just wanted to let you guys know about the warnings - since it doesn't prevent the plugin from working, it's not a major issue. Thanks so much!
