not an akeeba fault, but something is wrong with this site, if i hit REGENERATE (Your server config file may need to be rebuilt) it kills the site, i think if i regen .htaccess in AA i believe it also does, espescially if i ask it to redirect to non-www.
ive noticed that if i have siteground set as manual 8.0.30 ...then do a .htaccess creation, it reverts to sitegrounds managed PHP which by default is 7.4 or something low. i assume regen does too ??
any ideas at this point without access ?i can give access later if no idea :)
