WooCommerce

That message is designed to only show if the /wp-content/plugins/woocommerce/woocommerce.php file is not in the ‘active_plugins’ list. Generally speaking that means that the WooCoomerce plugin is not active, which is different from being installed.

My gut instincts are saying that you may have ‘installed’ WooCoomerce, but the plugin may not be ‘active’. Visit your plugins page, and try to ‘activate’ the WooCoomerce if it is deactivated. Even if you are sure about this without looking, double checking only takes seconds, so you may as well.

If that is not the problem, then try deactivating _both_ OpenTickets Community Edition and WooCommerce. Once they are both deactivated at the same time, then reactivate them both, in any order. This will reinitialize any installation steps that could be causing the plugins to not recognize each other.

If you are still having problems, try removing and reinstalling both plugins from www.ads-software.com. Sometimes the installation process may get interrupted, for one reason or another, and cause some initializations to not take place. This should rule that out.

If you are still having problems, then try deactivating all of your other plugins one at a time. If the message goes away after a specific plugin is deactivated, then it is probably causing some sort of conflict, and should be reported here ASAP, so that we can improve compatibility for it.

If none of these steps help, then maybe you and I can hook up, and I can get some sort of access to the installation, and help track this issue down. Or if that is not an option, then we can exchange a comprehensive list of plugins and themes that you are using so that I can setup an identical site on my server, and test out the issue. One thing we really care about is compatibility, so any issues like this should be investigated as soon as they crop up.

Let me know if any of this helps,

I found another thing that could cause this problem. If you got your version of WooCommerce from github.com by clicking the ‘download zip’ link on the right side column, that zip file contains a non-standard woocommerce plugin folder name. This non-standard name could also be causing this error to pop. For examle, if you download the ‘master’ branch from github using the zip file link I described, then your plugin will be installed at:

/wp-content/plugins/woocommerce-master/

causing the actually plugin bootstrap file to have the name:

/wp-content/plugins/woocommerce-master/woocommerce.php

Our plugin does not currently look for these non-standard plugin folder paths, but will probably do so in a future release now that I know this is a possible way to pop the message. We currently only look for:

/wp-content/plugins/woocommerce/woocommerce.php

The easiest way to solve this problem is to not use the zip downloaded from github, and instead use the WP plugin search feature in your plugin admin page, and install the version they have on www.ads-software.com instead.

Hope this helps,
