After upgrading from PHP 7.1. to 7.2 my site started to show warning for each tag (in each question which has one or more of them), which looks very ugly:

Warning: count(): Parameter must be an array or an object that implements Countable in /home/anton800/ask.myfinances.biz/qa-include/qa-base.php(720) : eval()'d code on line 10

The warning is shown both in the questions list and at the question page.

The issue is related to Advanced Tag Descriptions plugin - its file qa-tag-desc-layer.php calls count() on the 10th line:

if (count(@$plugin_tag_desc_list)) {
      'SELECT tag, title, content FROM ^tagmetas WHERE tag IN ($)',

Is it a known issue? How to resolve it?

A workaround: just remove the plugin (it is not possible to disable it in through the admin panel, so just move its directory elsewhere); anyway it doesn't work as expected (see also #3).

Yes it’s an issue with the plugin, you should report it to the developer. But this should also work, replace the 4th line of your example with

if (is_array(@$plugin_tag_desc_list) && count(@$plugin_tag_desc_list))

Here is another solution:

if (count(@(array)$plugin_tag_desc_list))
