I'll take a look at this.
in the meantime, you can set your error reporting to "simple" in joomla global config.

From what I am learning it seem to be a problem with a number of component, Module and Plugins thats having problem with Php 7.2...

Joomla recommends updating php to 7.1 or above so when I updated to php 7.2 this is when I started to get the above error. I have since updated all my components, modules and plugins. But music-collection is still at 3.0.6 I believe and haven't been updated in the last 5 months and there have been 3 updates to Joomla.

So I look forward for the next update and new features for Music-Collection...

Updated PHP to 7.2 and now I am getting the following error and would like to know how to fix it without lower PHP!

Warning: count(): Parameter must be an array or an object that implements Countable in /home/xxxxx/xxxxxxx/components/com_muscol/models/artist.php on line 170


Thanks

I have the same error. Fresch install Joomla 3.9.15 and PHP 7.4. All plugin and component are updated to the latest version. Error reporting to "simple" in joomla global config.

Is there anything new about it?
When will there be an update in general?

I have just published version 3.0.7 which should get ride of the PHP 7.2 warnings.
Please if you still encounter any, let me know!
thanks!
