Polylang issue

Hello there,

I’m having an issue with Courtyard and Polylang.
Everything worked ok until a couple of weeks ago when the website started returning 503 errors.

Every time Polylang is active I get the following error:

Fatal error: Allowed memory size of 134217728 bytes exhausted (tried to allocate 2 bytes) in /home/e42r59uc/public_html/wp-includes/wp-db.php on line 1972

Using Courtyard 1.3.6 and Polylang 2.5.4

Thanks in advance
