Try switching to the default theme (Twenty Seventeen) and deactivating all other plugins.
And then? I need it to work with our theme and all other plugins?
And then … contact the theme or plugin author to notify them that their code has a conflict with Contact Form 7. As this plugin is one of top 5 most downloaded and installed plugins in the WordPress plugins ecosystem, it would be a surprise to find any authors who were happy their code is not compatible with CF7.
Also note that there are no other widespread reports of PHP 7.2 issues with this plugin in the support forum. I run 4 sites that use PHP 7.2 and CF7 without any issues.
Good luck!
Thanks @pidengmor
This is not about compatibility or a conflict with Contact Form 7. I don’t think at all the issue has something to do with Contact Form 7. It was just that there seemed to be defective plugins or theme so I suggested deactivating all of them once to find the culprit.
@takayukister I think it could be helpful if you modified your response recommending people de-activate theme & plugins to include a brief explanation of why you are suggesting this approach. I’ve noticed that many new CF7 & WP users misunderstand your response.
For example:
This could be due to a conflict with your WP theme or one of the other plugins you are using.
Try switching temporarily (nothing will be lost when you switch back) to the default theme (Twenty Seventeen) and deactivating all other plugins to see if the problem goes away.
This is a technique commonly used in WordPress to find what is actually causing a particular problem.
If it does you can switch back to your theme & re-activate each plugin one by one to see when the problem occurs.
@simonesdesign I’m using PHP 7.2 and CF7 on dozens of sites without any issues.
