    Hey guys,

    i have a problem with installing the plugin. Whenever i want to install it, i get the following fatal error and my whole wordpress admin-page isn’t working anymore. I need to delete the folder in the plugins directory to get back to normal.

    Fatal error: Uncaught NinjaMutex\UnrecoverableMutexException: Cannot release lock in Mutex __destruct(): codeneric_phmm_migration in /var/www/web26647988/html/wp-content/plugins/photography-management/vendor/arvenil/ninja-mutex/src/NinjaMutex/Mutex.php:100 Stack trace: #0 [internal function]: NinjaMutex\Mutex->__destruct() #1 {main} thrown in /var/www/web26647988/html/wp-content/plugins/photography-management/vendor/arvenil/ninja-mutex/src/NinjaMutex/Mutex.php on line 100

    Can you please help me? How can i solve this problem? Is there an update necessary? I tried the actual plugin version as well as version 4.1.2

    Thanks in advance for every help!

    Hi,

    thank you for reporting the issue. Which PHP version and which OS is installed on your server?

    The error is related to a module which sets a lock on a file in your wp uploads folder (usually wp-content/uploads). Make sure that PHP has sufficient permissions to write in this folder.

    Hi,

    thank you for your reply! This helped me to find a solution for the problem. In the log files i found additonal errors which lead me to the mysql database.
    I previously had the website migrated via duplicator to another server – this caused the problem. I had to delete the whole plugin as well as the plugin files and folders in the “upload”-folder and then had to search & delete manually via phpmyadmin the remaining data from the plugin.
    It would be an improvement for further plugin development, that with de-installation of the plugin the database is cleared completely.

    Thanks again for your help!
