Hi and thank you for contacting WPML Support!

I will be happy to help you with this.

From what I see, your site is using an outdated version of MySQL on your server. The minimum recommended version is MySQL version 5.6 (and above).

Also, WP memory is 40MB so we need to raise that to at least 128MB.

Here is a list of the WPML requirements:

So, what I will need you to do is this (retry activating the String Translation plugin after each step):

1. Update the MySQL version to at least v5.6 (an admin of the server can do that usually)
2. Raise the WP memory to at least 128MB

You can add this code to your wp-config.php to increase WP memory:

/** Memory Limit */
define('WP_MEMORY_LIMIT', '256M');

Paste it just before:

/* That's all, stop editing! Happy blogging. */

These settings can be limited directly by your hosting provider, so I recommend you to contact and ask them to modify them directly. If you can get even higher values (like 256MB) it would be even better.

Please let me know if this solved your issue or if you still need help.

We have contacted our hosting provider and they have indicated that they are no longer working with MySQL and have switched to MariaDB instead. They have said that their current version of MariaDB should be recent enough for our uses and they cannot update it.

I see.

Did you at least manage to try step 2 and test after that to see if the issue is still happening?

Please let me know.
