After installing the latest version of Uniserver, I browsed to the plugins_detail.html page in the Uniserver manual and noticed that 1 of the listed plugins is "ZeroXI_php_6_0_0.exe". I tried clicking on the link next to the words "Modules download folder" and got the following error message:
The "/UniServer ZeroXI/Ze..r ZeroXI/ZeroModules" file could not be found or is not available. Please select another file.
Then, I tried going to the ZeroXImodules folder on SourceForge and noticed that there's no file named "ZeroXI_php_6_0_0.exe".
