it started giving these messages and it didn't publish any articles... | CyberSEO Pro | Support Forum

The message you are seeing that the creation of a dynamic property is deprecated is a warning, not an error. This is because PHP 8.2 and later versions mark the creation of dynamic properties as deprecated. This means that the approach used in the code is deprecated by the latest PHP standards and is recommended to be updated. However, deprecated code is still usable - it simply indicates that the code should ideally be updated to use a more modern approach.

This message will be fixed in the next release of the plugin to ensure compatibility with newer versions of PHP. In the meantime, the warning should not affect the functionality of your current code.

Regarding the issue of posts not being added, this is definitely unrelated to the deprecation warnings. To better diagnose why posts are not being published, please check the Login to see this link in CyberSEO Pro's dashboard. The log should provide detailed information about what the plugin is doing when trying to syndicate posts. If you can't see the problem in the Syndiactor log, just paste it in your next post here.
