The documentation says that if the installation is acting strangely to clear the cache and rebuild the index.
Under admin I have cleared caches.
It also informs me that the index was fully rebuilt in November, but I can find no function or documentation on how to rebuild the index in Tikiwiki, phpmyadmin, or MySQL. There is information on setting up a Cron job but this is currently outside my expertise.
On shared webhosting site with cPanel, Softaculous, etc
Please advise how to proceed.
PS. One strange thing happening is when I try to upload a file to the galleries it gets to 99% and then displays an I/O error (firefox) and Error 330 on Chrome. Until a few days ago uploads worked fine.
