We also plan to do extensive tests with this PHP version. * In the meantime, it is highly recommended to stick with PHP version 7 (e.g. 7.2, 7.3, 7.4) until 8 becomes more adopted and stable.

Can you let us know if this is still an issue? Did you manage to resolve it? * Thanks * Plugin Author [wipeoutmedia](https://wordpress.org/support/users/wipeoutmedia/) * (@wipeoutmedia) * [4 years, 5 months ago](https://wordpress.org/support/topic/php-8-errors/#post-15153112) * Hello there, * We have now fixed a number of compatibility issues for PHP version 8+ These fixes will be coming in the next CJT update (version 11.5). * We have tested the plugin with PHP version 8 and version 8.1 and found a couple of breaking changes, which has been fixed as well. We locally set up the environment with PHP version 8 and MySQL version 8 and tested the CJT plugin there. All is working well so far. * Thanks * Plugin Author [wipeoutmedia](https://wordpress.org/support/users/wipeoutmedia/) * (@wipeoutmedia) * [4 years, 5 months ago](https://wordpress.org/support/topic/php-8-errors/#post-15161524) * Hi there, * I am just letting you know that CJT version 11.5 has now ben released with the following changes: * * Compatibility: PHP version 8+ * Compatibility: MySQL version 8+ * Fix: Duplicate ID issue, which on rare occasions was fetching the ‘revision block’ ID for a newly created block causing an error for duplicate entry * Enhancement: If the‘ wp-content’ directory is renamed to something different (e.g. ‘content’), CJT will now find any custom content directories and install correctly.
