Cannot modify header warnings

[Norm6257]

Hi,

I'm noticing a number of cannot modify headers warnings in the event logs (see below.) I think these are all happening as a result of wp-cron running and Ajax Login getting called. Maybe do a check to see if doing wp-cron, and if so, you probably don't even need Ajax Login.

Thanks, -Norm

Hi Norm,

what plugin number version are you using? free or Premium? Thanks

[Norm6257]

This is with the free version 1.9.0, though I also have the Pro version. If you want, I can upgrade this site to the Pro version and see if the issue still exists.

[stranoweb]

Yes would be nice.

Also, finally the request you did to open the popup by querystring parameter is now available on the new Premium version update 1.9.3

[Norm6257]

Hey, I noticed that you added the query param option. :) Thanks!

I tested 1.9.3 Free and Premium and both still exhibit the 'can not modifty headers' issue. I'm almost positive this is occurring when wp-cron is called.

[stranoweb]

Can you please let me know at what line is now the warning message?

[Norm6257]

It's now on 1314 ... that's with the Premium version

[Norm6257]

Any update on this issue?

[Norm6257]

Any update on this issue? It's really adding a lot of entries into the server error log like:

Hi Norm,

I think there's some other plugin or the theme that is outputing HTML content before we write our cookies. If you can do a test in a staging enviroment disabling all the plugins but ours and see if the error disappears. If so, you can active the plugins one by one and check error log.

Let me know. Best

[Norm6257]

It seems to be some conflict between SWAL and WooCommerce. Either one of those plugins alone seems to be fine. But when I run both SWAL and WooCommerce (no other plugins active), then I get the Cannot modify header error messages.

I don't know if the issue is with SWAL or WC, but with WC being the 1000 pound guerrilla in the yard, I pretty much what they will say...

[Norm6257]

Are you able to replicate this issue with just SWAL and WooCommerce? If not, let me know and I can set up a test environment that has the issue.

Any update on this? It's really causing a lot of entries in the error log. Here's just a sample:

Hi Norm,

Unfortunately no news yet, despite i'm trying to send header information before it WooCommerce, it always wins the race. I know it quite annoying, however that's a PHP warning, it means that doesn't break the script. Will try to come up with a solution soon.

What caching plugin are you using on this website?

[Norm6257]

I use Litespeed, though when replicating this issue I had just WooCommerce and SWAL activated. Litespeed was disabled, so no caching.

I've fixed the issue, the Premium version update is already available. Free version update will follow soon.
