Andrey WPML Supporter since 06/2013 Languages: English (English ) Russian (Русский ) Timezone: Europe/Kyiv (GMT+03:00)	Thank you for contacting WPML support. Could you please try the following and let me know the results? 1. Deactivate the OTGS Installer plugin. 2. Activate WPML Multilingual CMS. The OTGS Installer plugin is not required when WPML is already activated. If the fatal error still occurs, please enable debugging and share the full error message from your debug.log file. Here’s how: 1. Open your wp-config.php file and add (or update) the following lines just before: /* That's all, stop editing! Happy publishing. */ define( 'WP_DEBUG', true ); define( 'WP_DEBUG_LOG', true ); define( 'WP_DEBUG_DISPLAY', false ); 2. Replicate the issue. 3. Open the file located at /wp-content/debug.log. 4. Copy and paste the full error message here, especially any entries related to WPML. This will help me better understand what is causing the fatal error.

danielH-163	Hi Andrey, sorry, but there is no WPML Plugin shown at all in the list of installed Plugins. After activating OTGS I get a frame in the plugin list with: --- Need to translate your WooCommerce store or add multi-currency support? Bitte installieren Sie WPML Multilingual & Multicurrency for WooCommerce, um die Übersetzung von WooCommerce zu ermöglichen. Installieren und aktivieren --- If I klick the install button there, nothing happens

When you log in to leave your next reply, you will find the needed fields below the comment area. The information you will enter is private, meaning only you and I can see and access it.

danielH-163	Does this mean, that we already had a license for our company. I was surprised to read something about a lifetime key in the message. It may be the case. In the past it was done by another guy in my team and I don’t know wether he worked with you guys already. Can you check for license registered on a @mark3d.de email ?
