TOPIC:

A few months ago, I reported some errors and their fixes during the migration sites in Apache/2.4.46, OpenSSL/1.1.1j, PHP/8.0.3 and JEM version 2.3.0. Today I am updating JEM version 2.3.1 and I am experiencing the same errors. Also, I will point them out to you once again below hoping it can help:

...\administrator\components\com_jem\views\categories\tmpl\default.php
An error has occurred: 0 implode(): Argument #2 ($array) must be of type array, string given (line 190)
Correction: <input type="hidden" name="original_order_values" value="<?php echo implode(",", $originalOrders); ?>" />

Correction: iCalUtilityFunctions::$baseDelim .= $base[mt_rand( 0, $len )];

After these few fixes, JEM works perfectly.
Have a nice day staying safe and healthy,

Thank you Joel, your input is welcome!

Unfortunately PHP 8 compatibility was still not in the focus.
Even the Joomla! 4 migration has a higher precedence, as far as I know.
But if these few patches do the full job for PHP 8, it is really time to rethink this.

Sorry, but it is strange, because this is your first post here (at least with this username)?
But thank you anyway, we will have a look, how to integrate this.
I tested, it worked with php 7 too!

There is a problem in output.class.php:

Deprecated: Required parameter $params follows optional parameter $view in /srv/www/vhosts/mysite.ch/httpdocs/components/com_jem/classes/output.class.php on line 848

but when I change from:
to:
I get an error calling the eventdetailview
call to a member function get()
EDIT:
When I change to:it seems to work but gives an error:
Warning: Attempt to read property "map" on string in /srv/www/vhosts/mysite.ch/subdomains/intra/httpdocs/components/com_jem/classes/output.class.php on line 854

who knows a solution?

Indeed, you're right, I posted my message on the Joomla forum because at that time, it was impossible to create an account on the JEM forum.

>I tested, it worked with php 7 too!
In Fact, I had tested these modifications in PHP 7 and it worked but I forgot to specify it.

Have a nice day ahead
