I do not know why I get this error every time I want to activate WPML Multilingual CMS

Warning: require_once(/mnt/web315/b2/06/59256406/htdocs/WordPress_04/wp-content/plugins/sitepress-multilingual-cms/vendor/otgs/ui/loader.php): failed to open stream: No such file or directory in /mnt/web315/b2/06/59256406/htdocs/WordPress_04/wp-content/plugins/sitepress-multilingual-cms/sitepress.php on line 97 Fatal error: require_once(): Failed opening required '/mnt/web315/b2/06/59256406/htdocs/WordPress_04/wp-content/plugins/sitepress-multilingual-cms/vendor/otgs/ui/loader.php' (include_path='.:/opt/RZphp72/includes') in /mnt/web315/b2/06/59256406/htdocs/WordPress_04/wp-content/plugins/sitepress-multilingual-cms/sitepress.php on line 97

Thank you for contacting us. This looks like WPML was not installed correctly. Please follow the steps below:

- Back up your site (files and database)
- Click on the Plugins > Installed Plugins
- Disable and remove the WPML (it will not affect your translations)
- Download the WPML again (
- Click on the Plugins > Add New > Upload Plugin
- Select the downloaded file and install the WPML
- Enable the WPML

Following these steps, does the problem still persist?

Thank you.
