This plugin will crash dokuwiki

I copied related error message from /var/log/apach2/error.log . I understand you may have no time to fix it since this plugin has not been updated for almost 6 years. Cheers.

Seeing same issue. Not sure how to resolve... =(

Just Edit the files mentioned in the error log.

If you're working with PHP code of other people this will occur many many times. This happens when a function / class extends an existing one. When the existing one gets an update and the passed function(String $data1) gets changed to say function(int $data1) this compatibility problem will result in this Warning. In many cases it will just work if you change the passed variables in the function declaration as mentioned in the error.log.

So just change it to "handle($match, $state, $pos, Doku_Handler $handler)" (just an example).
