Do you have the `php-imap` PHP module installed? Run the command `rpm -qa | grep php` (CentOS) or `dpkg -l | grep php` (Ubuntu) and see if it is listed. If not, try installing it through the package manager `sudo apt install php-imap` (CentOS) or `sudo yum install php-imap` (Ubuntu) then restart your web server and the PHP-FPM process (if using PHP-FPM). **Apache:** `sudo systemctl restart httpd` (CentOS) or `sudo systemctl restart apache2` (Ubuntu) **Nginx:** `sudo systemctl restart nginx` **PHP-FPM:** `sudo systemctl restart php-fpm` ---

5.4 is not supported anymore by Mautic. You need to upgrade PHP and its modules to PHP 7.2 or 7.3. ---

I had the same issue, the problem is that the console could use a different folder or instance of PHP. For instance, my mautic folder-project worked with PHP 7.2, but when I was in the console, the active PHP was 7.4 and this version of php did not have the imap library. I just installed the imap library in php 7.4 and it works! ---

php -v in the console to see the active php could works ---

I am now experiencing this issue, I have php 8 IMAP working, it shows in the system info tab as enabled, Any ideas on how I could trace this issue? ```auto In Mailbox.php line 542: [Symfony\Component\ErrorHandler\Error\UndefinedFunctionError] Attempted to call function "imap_search" from namespace "Mautic\EmailBundle\MonitoredEmail". ``` [REDACTED] ---

php8 is not supported yet … need to be at php 7.4 ---

I’m on 4.4 which release PHP 8 support, but either way, I upgraded to 8 to try to remedy the issue but it didn’t work, it started just the same at 7.4 ---

I don’t remember about 4.4 supporting php8 then … You could be right however I been seeing posts in here recommending to stay with 7.4 until Mautic 5 is released. ---

Here is that release > **[Release Mautic Community 4.4.0 · mautic/mautic](https://github.com/mautic/mautic/releases/tag/4.4.0)** > > This is an out-of-cycle release which provides PHP 8.0 support to Mautic 4 users, and some other bug fixes. This should allow Mautic users to update their PHP versions before PHP 7 reaches end of l... The issue still is not that one however, as PHP version does not fix the issue, now only seeing it with ```auto php /home/crm.grou.com/public_html/bin/console mautic:email:fetch -v ```
