I have been using an old plugin that uses custom post types and I am changing to a newer plugin with better functionality (don’t wish to to start a war of words so please don’t ask which plugins).
I have migrated hundreds of custom post types in the WordPress database table via mysql statements to the new plugin structure successfully – no problem.
The issue is that the old plugin content contains html tags such as <p>, , etc. These are now being displayed on the public facing pages of the website. I.E. ‘<p>Hello World</p>’ – rather than ‘Hello World’.
If I open an individual CPT in the admin area, do absolutely nothing else but then re-save it – it successfully strips all the unwanted html tags.
Does anyone know what hook activates this process and/or how I can process this for all the custom post types?
