The website has been updated from Joomla 3 to Joomla 4 today.
With the upgrade to Joomla 4, I have switched from ChronoForms to Convert Forms.
I no longer recommend ChronoForms as each new version needs to be relearned as it operates differently and there is never enough documentation when the new version is released.
I have also updated the PHP ICO version from 1.0.2 to the latest version 1.0.4.
I do not anticipate any issues but let me know if you notice anything unexpected!
