Hi, after you installed the latest plugin, did you go to Extensions -> Modifications and clicked the refresh button? Your website html seems staled as 'FACEBOOK_CUSTOMIZATION_GREETING_TEXT_CODE' variable was not used in the latest plugin codebase any more, you need to follow the OpenCart plugin installation steps to properly build the html.

Hi,

I am sure that I did Extensions -> Modifications and clicked the refresh button.
I uninstalled and installed again and then followed the instructions in https://github.com/facebookincubator/Facebook-For-OpenCart/blob/master/INSTALL_GUIDE.md#setup-for-facebook-business-manager-page-pixel-and-catalog
but again failed. So I had to uninstall it again.
The setup gets completed but when i click add2cart it shows 500 error.

Also I followed the instructions "For OpenCart 3.x, you need to perform an additional installation step" and notified that the Module Facebook Ads Extension is not in my list. Is it problematic?

happy to have a zoom chat or share my screen if that helps.

Any ideas?

Thanks.

Hi, could you install plugin version 3.0.1 instead? https://github.com/facebookincubator/Facebook-For-OpenCart/tree/v3.0.1

Hi,

Just did but again failed. :(

Same issue. When clients go checkout page throws an error "page not found" on route=checkout/checkout.

For info I'm having the same issue. Wasn't there on the previous version of the extension however after updating yesterday my Cart and Checkout pages display the 500 Internal Server Error page. When I disable the extension the issue goes away so it's definitely this extension.

Would love a fix as everything else (including the Messenger button) works perfectly.

i'm following this thread because i have the exact same issue using latest FBE v3.
cart and checkout page leads to "page not found"

The solution here, is to uninstall all versions of the plugin that you may have installed and then install the latest version only and then refresh modifications.

Constant FACEBOOK_CUSTOMIZATION_GREETING_TEXT_CODE is not used by the latest version and there's a conflict when you have a previous version installed along with the latest one.

@konstantinosbotonakis I uninstalled all versions of the plugin and installed the latest version and refreshed modifications but AGAIN FAILED!

[alireza-shamakhy]

Facebook team, is there any updates regarding the issue? appreciate if you can fix it.
