Internal Server Error on “Place Order”.

Hi @gateruner

What version of our plugin are you using?

Could you provide us the WC log? Go to WooCommerce > Status > Logs

Im using Version 2.4.7 for the PDF invoices. Looks like WooCommerce is Version 4.0.0 A option to update woocommerce just showed up as well. Ill wait to hear from you to update that

Here is the log.

Hi @gateruner

There is no errors there from our plugin. Can you test deactivating all the other plugins and keep only ours and WooCommerce and see if the problem persist?

Also if you could check the PHP error log would be good.

Here is the followup. I disabled all the plugins and the theme and went back to a 2019 theme to test this. The only plugins that are enabled at this time are as follows: Woocommeerce
WooCommerce PDF Invoices & Packing Slips
WooCommerce PDF Invoices & Packing Slips Premium Templates

*Here is what happens when I do the following.
Leaving all 3 of those plugins and try to view a pdf invoice it brings up the following page error.
There has been a critical error on your website.

*If i disable the Premium Templates plugin then it results in the following page being displayed.

I am not sure how this isnt some issue related to one or the other of these plugins. I looked at the woocommerce log that you mentioned before and it has the following in it. Im not sure its releveant since the rev slider is not active now.

*Final note. Just tried to place an order with the Premium Templates plugin activated and it created the internal server error. Disabled that plugin and the order was allowed to go through. So to me this issue has to reside with the Premium Templates plugin. Hopefully you can assist me with this based on the following tests.

Still looking to you for any assitance.

Hi @gateruner

Because you’re using Premium Templates and that’s a paid plugin we can’t deliver support here. Please contact us in [email protected] and we will try our best to help you.

Ok thanks alex
