Installing Community Builder modules

Had previous problems installing Communit Builder, due to folder Create and file Copy problems.
Permissions I know, but could not solve, even with 777 throughout the site.
Now resorted to copying to folders and using Discover.
This appears to work.
Just got to get the last 2 modules, mod_comprofilerModerator and mod_comprofilerOnline
However, these are giving errors when reading the XML files, during the Discover step.
Not continuing with the INSTALL, until this is resolved.

Failed loading XML file
/var/www/vhosts/ModelPipeline.com/httpdocs/modules/mod_comprofilerModerator/mod_comprofilerModerator.xml
XML: failed to load external entity "/var/www/vhosts/ModelPipeline.com/httpdocs/modules/mod_comprofilerModerator/mod_comprofilerModerator.xml"

Have you read the FAQs? Have you read all the installation docs and followed them step-by-step? Have you tried the expert installation, also documented in the installation docs?

Sounds like you have serious permission issues with your hosting environment.

Please PM me backend info and I will take a look.

Yes, I've read all the installation documentation. I cannot locate an "expert installation" documentation. Where is that?
However, I do not think I am doing anything complex.
I think the error relates to using Joomla v1.6.1 and the XML file for mod_comprofilermoderator, which has comments in it about not being readable by Joomla v1.6
I'm just not sure if I should proceed with the install, if the Discover is reporting these errors about the XML file.

Still willing to look closer if you PM backend access info.

(expert upgrade/install is in the readme files in tha package)

Got PM, thanks.

Your upload_max_filesize is set to 2M.

You need to increase this to at least 4M as stated in the Installation document and the READ me files.

Please ask your host to assist you in this change as each host might have different method to do so.
