WordPress critical error since yesterday

Hi Pankajabcd,

Thanks for your message.

Sorry to hear about this issue. We will need some more details to investigate this and fix it as I am not getting this on my test website.

Can you please turn on error logging for your site and then let us know which specific error is appearing so we have a clearer idea? https://www.ads-software.com/documentation/article/debugging-in-wordpress/

Looking forward to your reply.

All the best.

I had rolled-back to previous version of Pixel Cat. So, right now error might not be visible.

Let me enable debugging and upgrade to latest version.

I have replaced the backend URL and now sharing the error with you.

There has been a critical error on this website.

Hi Pankajabcd,

Thanks for your reply.

So there are no other errors appearing in the log?
You can probably roll back to the previous version and I will alert the development team to have this investigated.

Do you have Easy Digital Downloads installed on your website?

Thanks and all the best.

Hi Pankajabcd,

Can you tell us which version of WordPress you are using?

Looking forward to your reply.

All the best.

Hi Pankajabcd,

Thanks for that information.

We made an update that looks to fix the issue you had. Please update to the latest version of Pixel Cat and see if your issue is now solved.
If the same happens as before, please kindly check to see what the error logs show so we know what to work on next.

Looking forward to your reply.

All the best.

I have upgraded. The website error is gone. You can check the same in the given link.

However, by default, after placing the pixel, it doesn’t active Page Views event anywhere.

Do I need to apply Page Views for each of the page / blogs manually?

Hi Pankajabcd, I hope all is well.

Sorry for the trouble with that. There has been another update to Pixel Cat that looks to fix this. Please update to the latest version of Pixel Cat.

If you have any further questions, don’t hesitate to let us know.

All the best.

Still its not placing Page Views in any page

Hi Pankajabcd,

Thanks for your reply.

Are there any error messages appearing in the log?

Do you have any caching plugins?

Have you tried turning off the other plugins to make sure there are no conflicts? Guide here.

I see your site is on a subdomain. Do you know if the pageviews are appearing on the main domain?

If you have any further questions, don’t hesitate to let us know.

All the best.
