Php Warning: Array_Merge(): Argument #2


I am running ver 4.3.3

For the last 2 weeks I have started getting this error

PHP Warning: array_merge(): Argument #2 is not an array in /home/mydomain/public_html/app/Tygh/BlockManager/Block.php on line 720

Not sure what is triggering this since there have been no changes to the cart over the last few months. This error has started generating itself only in the last 2 weeks

Can anyone please help what this means and how can this be resolved. it is filling up my error log file quite quickly

you installed any addon or done any custom work in last 2 weeks . if yes then may be its happens due to some third party addons.

The line in question is:

        $params = array_merge($params, $block['content']);

The error is stating that $block['content'] is not an array. The code is the same in the current version so I would probably try clearing the cache (delete files in /var/cache/) and monitor the log for the error.

Thanks let me try your recommendation
