How to rebuild the index
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.
Tikiwiki 12.6
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.
