Haven't been able to hunt down the right log to point me to the right adjustment, nor find anything on the net to help thus far. For some reason I have a feeling that it is something in litespeed (lsws), or whm. I have a faint memory of during initial setup config for lsws coming accross some 'concu...

Horde support will be removed from cPanel & WHM starting with Version 108. This is because Horde does not support PHP 8.x, and PHP 7.4 reaches End of Life in November 2022. What does this mean for me or my customers that use Horde? Our Webmail offering will be focused on Roundcube going forward. You...

Practically all data sent over the Inte et today is at risk in the future if a sufficiently large and stable quantum computer is created. Anyone who captures data now could decrypt it.Luckily, there is a solution: we can switch to so-called post-quantum (PQ) cryptography, which is designed to be sec...
