We have launched SitePad 1.1.5 in the Stable branch.
1) Added support for CentOS Web Panel. Refer to the following guide on how to install SitePad in CentOS Web Panel.
2) [Bug Fix] : In cPanel, the SitePad Website Builder – Themes category was not visible when “Use X-Frame-Options and X-Content-Type-Options headers with cpsrvd” setting was set as “On” from WHM -> Tweak Settings. This is fixed now.
