I'm trying to install SMF 1.1.21 on my website. It apparently doesn't want to be installed. I can tell because I got an HTTP 500 ERROR. Is 1.1.x no longer supported?

Hello! I'm unable to reach my forum--I get HTTP ERROR 500.

Unfortunately, I have no idea what version of Simple Machines it uses, other than I know it's very old. (Forum was started about 13 years ago.)  I had an admin who made modifications to the SM software for me, and coded my website, but staunchly refused to install the recommended updates over the years for fear the modifications would be lost. She passed away last year, now the forum is unreachable, and I'm stuck.

Can anyone help? Thank you!

I have quite a dated forum and now having issue with odd codes appearing ,the theme is black rain v3 and version 1.1.21

this is the image i get when i use with  odd codes at the top,any help would be appreciated

ok, i am the so called admin for a forum using version 1.1.13
and i need to upgrade to something more current as hostmonster does not support this version any longer
i had them reset to an earlier (php?) so that we could continue with the use of the forum, but need to upgrade so
we can then have hostmonster do their thing and get us going for down the road.

i have done a backup of the forum today, so i have everything, and currently it is still operational, however i have had
a report  of a glitch when trying to post, the topic line does not show anything but (new), and this happens only intermittently
so i think it really past time to get an upgrade done

if memory serves me, years ago i moved from an earlier version to ver. 1.1.13, and it was done from the admin panel
but i don't see that ability now?  maybe i am missing something? probably? (most likely)

the forum is microcogen.info  if that is important to the process or helps in any way?

thanks in advance

Now what?

Suddenly this started with nothing done on my end.  Still on PHP 5.6.  Can't access my SMF chatter.princessonly.com/
