PHP Warning: Illegal string offset..

Version 7.4.1 was released to address the illegal string offset issue.

* Fixes an unintended backwards-incompatible change which caused “Warning: Illegal string offset ‘url’ in”.

Can you try and gather as much information for us as possible? Please perform the following:

1. Make sure the issue doesn’t persist when Yoast SEO is disabled.
2. Check for conflicts.
3. Check for JavaScript errors with your console.

If you perform a conflict check and find that the issue still occurs with all other plugins (except Yoast SEO) deactivated and a default theme like TwentySeventeen, can you confirm that the Illegal String Offset issue still occurs?

I tried everything you said but nothing worked. I reverted back to version 7.3 right away, and everything is fine again.

Yoast SEO v7.4.2 has been released. Can you please update the plugin to the latest version to check whether this resolves the issue?

I already updated to v7.4.2 and still seeing errors/warnings.

Hello,

I have also this problem on sites with png images.
On sites only with jpg there is no problem.

I use version 7.4.2 and wp 4.9.5
