I noticed this error in my website popping up: ERR_SPDY_PROTOCOL_ERROR.
It happens when I order 1 certain product > fill in the fields > press Add to cart > the product gets added to cart and button shows with "continue shopping" > fill in the fields and add the product again to the cart. Then I get the error all the time. I'm not the only one getting the error, a lot of my visitors are getting the error.

Searched google a bit but clearing my cache, cookies, etc. won't solve the problem.
Currently in Firefox and Chrome.

Updated today to google chrome v70 but still getting the error.2 years, 8 months ago #1062382
We have checked your site and found the issue from some 3rd plugin.
The plugin not compatible with WooComemrce 3.4.6.
Please check it again.

It has the conflict with the "WooCommerce Advanced Product Quantities" plugin. When you enable the plugin and debug, it will show the notice "PHP Notice: product_type werd verkeerd aangeroepen".
As I see, you have fixed the issue with "ERR_SPDY_PROTOCOL_ERROR", the product page works fine. If still have the issue, please let us know again.
With the custom CSS, we don't change anything on your site. Just try to disable some plugin to check the debug.
Please check it again.
