DEBUG-Message

Does this happen on all menu options? Try Cron > WP Cron Schedules, that should be a short one. I’m wondering if the large output buffer of some of the options may be at fault.

Do you have WordPress debugging mode enabled? Are there any errors logged that could be set aside for now by deactivating plugins or selecting a default theme?

Thank you for your answer, Chris.

I’ve deactivated all plugins and then activated one-by-one. It worked until I activated the Yoast SEO-Plugin (https://yoast.com). When I’m activating Yoast SEO, Debug This stops to work.

Maybe because Yoast is using as well %%SOMETHING%% to use Meta-Replacements.

Any ideas?

Maybe it would help to get in touch witch Yoast?

Thanks for narrowing it down, Dan. I will start digging.

Any news so far?

I have not been able to reproduce the problem on a simple WordPress installation.

Two things we can try:

1. Edit debug-this/_inc/debug-template.php and change the single delimiters to double: %%DEBUG%%.

2. Export your SEO settings and send them to me via wpmission.com so I can replicate your configuration. Remove any sensitive info, of course.
