Blank homepage on mobile

Hi guys,

I have a problem that it seems related to Squirrly SEO.

Almost everyday, my homepage is blank. This seems to happen only on mobile.

When I cleared my homepage cache. My homepage is ok until the next time.

It happens few times a week, but I don’t know exactly when it occurs.

First time I had this problem was at the end of July.

Here are few lines from my PHP error log :

[06-Nov-2020 17:50:56 UTC] Erreur de la base de données WordPress Commands out of sync; you can’t run this command now pour la requête SELECT * FROM wp_posts WHERE ID = 7107 LIMIT 1 faite par shutdown_action_hook, do_action(‘shutdown’), WP_Hook->do_action, WP_Hook->apply_filters, wp_ob_end_flush_all, ob_end_flush, SQ_Models_Frontend->getBuffer, apply_filters(‘sq_buffer’), WP_Hook->apply_filters, SQ_Models_Frontend->setMetaInBuffer, SQ_Models_Frontend->getHeader, apply_filters(‘sq_json_ld’), WP_Hook->apply_filters, SQ_Models_Services_JsonLD->generate_breadcrumblist_data, SQ_Models_Snippet->setHomePage, get_post, WP_Post::get_instance

I contacted the wp rocket plugin support with my php logs and they told me that it was related to Squirrly.

Here are an extract of their reply : “I’m afraid that none of the errors are related to WP Rocket. Both seem to be related to the Squirrly SEO plugin.
What usually happens on these cases is that another plugin triggers the white/blank screen error that WP Rocket just happens to cache.”

Could you please help me to identify and fix this problem ?

I have Squirrly SEO Version 10.2.00

Thank you.
