type E_ERROR Connection lost. Saving has been disabled… / Critical Error
-
Since 2-3 days I’m having this “critical error” in my Woocommerce online shop.
Every time I’m trying to save/update a product, after 35-45 seconds, it says (in the backend header):
“Connection lost. Saving has been disabled until you’re reconnected. We’re backing up this post in your browser, just in case.”
Then it takes about another 1,5 minutes (2:10 in total) when the following message appears:
“There has been a critical error on this website. Please check your site admin email inbox for instructions.”
Since the error appeared, I received 3 emails:

#4I already have deactivated the Rank Math plugin, but that didn’t help at all.
Also I can neither activate nor deactivate plugins in the backend. I need to use FTP, change the name, so it gets automatically deactivated, and then change the name back (the plugin then stays deactivated).
When I try to deactivate plugins in the backend, it takes up to 4-5 minutes until time out. After going back, the plugin is still activated.
When trying to activate an incative plugin, it also takes a long time until time out, but after going back or reloading the plugin page, that plugin is activated.
Last, I tried to deactivate the PayPal plugin and after more than 4 minutes the following error came up:
“Plugin could not be activated because it triggered a fatal error.
Fatal error: Cannot redeclare wc_gateway_ppec() (previously declared in /www/htdocs/w00f568a/WEB_moleculecargopants_WP-Woo_2020-10/wp-content/plugins/woocommerce-gateway-paypal-express-checkout/woocommerce-gateway-paypal-express-checkout.php:38) in /www/htdocs/w00f568a/WEB_moleculecargopants_WP-Woo_2020-10/wp-content/plugins/woocommerce-gateway-paypal-express-checkout/woocommerce-gateway-paypal-express-checkout.php on line 38”BTW: Saving/updating pages works just fine.

– I have used a database backup from a couple of days before (when everything seemed to be all right).
– I have tried another theme (Twenty Nineteen).
– I have used the “Check Conflicts” plugin and deactivated all plugins except for Woocommerce.
Nothing helped!
– Another website on the same server (not wordpress / Woocommerce) works just fine.
– Internet works just fine.
I have read many posts on many different websites with a similar issue, but nothing lead me to any solution.
Please can anyone help?
