Hallo,

I am currently testing my websites under Joomla 5 and have installed the latest RL extensions. Articles Anywhere Pro 15.0.4 unfortunately does not work (errors see below), with the direct predecessor version it still worked.

Errors:

No, it is an internal XAMPP installation - just for testing Joomla 5. But I will see to install an instance on my public webserver. Not today - I will inform you ASAP. 🙂

Main error message: "0 array\_keys(): Argument #1 ($array) must be of type array, int given"

The errors also occur under Joomla 4.4.0 with PHP 8.2.4 when the RL extensions are updated to the newest versions.

Main error message: "0 array\_keys(): Argument #1 ($array) must be of type array, int given"

So I did some more tests:

In a new Joomla 4.4 instance with the latest Regular Labs extensions the error does NOT occur.

So I disabled all none-core extensions on the website in question, except for the latest Regular Labs extensions - the error occurs.

Then copied from my live website the directory: libraries > regularlabs to the test website - the error is gone.

Apparently there is a conflict with a library file that is important for Articles Anywhere. Which one? I haven't gotten that far yet. But maybe it is a hint.

With a trial and error test I found the file that causes this problem: StringHelper.php (version 23.10.17780)

A replacement with older version 23.8.22797 fix the problem for the moment.

Sorry, could not reproduce the error so far in a standard Joomla 4.4.0 installation. Looked at the error messages again instead.

The main error message was:
array\_keys(): Argument #1 ($array) must be of type array, int given

With system debugging enabled, there were lots of other error messages. The second one was:
array\_keys() | JROOT/plugins/system/articlesanywhere/src/DataGroups/Helpers/Text.php:487

Exactly in this file (Text.php) I made the following change in the given line 487, which was successful. 



I changed the code: $words = RL_String::countWords($string, 2);
to: $words[0] = RL_String::countWords($string, 2);

Perhaps this is more helpful for you.

Works! Good job. 🙂
