Joomplu and PHP8 error

Hi, I am slowly planning to upgrade onto PHP8, only encountered minor issues which were easily fixable, but this one gives me a headache. Joomplu throws this errors on frontend. Can one of the admins tell me how to fix this quickly?

Warning: plgContentJoomPlu::route(): Argument #1 ($matches) must be passed by reference, value given in C:\wamp64\page\plugins\content\joomplu\joomplu.php on line 455

MrMusic,

sure I know, but in development enviroment this is one hell of an issue!

I can literally scroll around it, but if there is anything I can do to fix it (sorry too lousy dev to figure out myself), then it would help a lot

See, thats why I always come here to ask for support because MrMusic is the right guy to ask. It has fixed the issue and no warning is now being shown! Thanks!
