Ja Sugite cannot run on PHP 7.3.
I recently upgraded my server and found one of my sites did not work with PHP 7.3 forcing me to roll back to 5.6. The site is www.oldgrowthgardens.com if you are just curious.
Is there a plan to upgrade it so it works on newer servers? The Joomla ver. is 3.6.5. The backed says it's all up to date.
