vanessaM-11	Background of the issue: I am trying to edit blog posts on my website using the dashboard editor. I have been working with my tech maintenance team (NerdPress) and my host (BigScoots) to resolve speed issues. My host has identified multiple error logs coming from WPML. The issue can be seen on the dashboard editor when editing a blog post. Symptoms: The editor is really slow and barely functions. At times, I encounter critical errors on the site, making it impossible to work. Questions: How can I resolve the speed issues with the dashboard editor? What can be done about the critical errors occurring on the site?

Carlos Rojas WPML Supporter since 03/2017 Languages: English (English ) Spanish (Español ) Timezone: Europe/Madrid (GMT+02:00)	Hello, Thank you for contacting us Generally, the performance issues are not caused by the WPML plugins, but by an interaction with third-party functionalities. I kindly ask you to follow these steps, in this order, to isolate the cause of the problem and get more information about it: - Create a full site backup or create a staging site with a copy of the live site (you can use the WP Staging plugin for free to create the staging site) - Update any outdated plugins or themes - Flush any cache memory that might exist - Deactivate all plugins, including the WPML ones - Activate a default WordPress theme, like Twenty Twenty - Activate the WordPress debug mode by following the steps described in this guide: https://developer.wordpress.org/advanced-administration/debug/debug-wordpress/ - Activate the WPML plugins - If the issue disappeared, start by activating the theme and then the rest of the plugins, one by one, until the issue appears again and you find the culprit - Also, check if there is any error related to the performance issue in the debug.log file located within the wp-content folder Please let me know the results of the steps described above. Looking forward to your message. Regards, Carlos
