I'm getting a PHP error when I go to the back end of the Purity III template:
Deprecated: implode(): Passing glue string after array is deprecated. Swap the parameters in .../plugins/system/t3/includes/core/admin.php on line 205
When I go to the admin.php file to "swap the parameters" what I see in line 205 is, but I don't know enough PHP to understand what I'm supposed to swap with what:
T3Admin.eids = [' . implode($eids, ',') .'];
I'm using PHP 7.4 and the Template version is 1.2.6 which is apparently the latest version. The front end of the site seems to be fine and I was able to make changes to the MegaMenu successfully, but I don't like leaving errors unresolved. In another forum post about the same issue back in December 2020, the person was told to disable error reporting for the server, but that will apply to all possible error messages, not just for the template, which doesn't seem very wise.
Is there a fix for this error? Is there something else I can do, say in the admin.php file, that will resolve it without disabling error reporting for my whole site?
Thank you in advance.
