As of 2022-10-25, Tiki doesn't support PHP 8.0 or 8.1 for reasons explained here: https://tiki.org/forumthread78628-Tiki-24-and-PHP-8
There is no point in reporting bugs on PHP 8.x unless you have the development skills to actually do the work, on you have financial resources to sponsor the work.
((Tiki24)) and ((Tiki25)) work beautifully on PHP 7.4.x
Some web hosting companies will cease supporting PHP 7.x as soon as PHP itself ceases support (November 2022). However, other hosting companies continue to offer it. Some charge extra for this service because
* They want to incite clients to move to PHP 8.x which is better and uses fewer resources (hosting company saves on resources)
* To help cover the cost of security backporta
