Just subscribed to the docs to get 1.2RC2. Downloaded and unzipped the file.
I'm using J1.5.6. Tried to install the component. Entire page goes blank with the url pointing to the administrator/index.php page. Haven't enabled PHP errors, but the readme doesn't point to what to do in this case.
This is not an upgrade. Never got to the module installs.
Very disappointing, especially since I subscribed expected this to at least install. I think the subscription concept is now questionable in my mind after I was willing to give this a try. If I pay for something, even if it is a release candidate, I would expect installation to either not be an issue, or at least some documentation of what to do for this kind of installation error.
Maybe you have a solution that can restore my confidence?
I'm sorry to read that.
Well, first of all thanks for your support to the project

.
To address your issue, CB 1.2 RC 2 installs fine on most servers (all those with reasonable capacity and correct settings).
Maybe you missed in last paragraphs of the README.TXT file, which are refered to from the last note of step 3) of the README step-by-step install instructions, you have the troubleshooting section:
IN CASE OF FAILED COMPONENT INSTALL:
- Blank screen: check error logs of your webserver, or enable PHP errors display.
Or try both fixes below blindly.
- Maximum Execution time reached:
On very slow servers, IF installation timeouts (not seen yet): you
can fix that as follows: Open file:
- joomla 1.0/mambo: administrator/index2.php
- joomla 1.5: administrator/index.php
and add line
set_time_limit( 240 );
right after the <? line, remove directories components/com_comprofiler
and administrator/components/com_comprofiler and re-install.
- Memory exhausted error (sometimes Error 500):
Joomla 1.5 with legacy ON and FTP layer ON on PHP 4.x may give error
Memory exhausted if memory limit is 8 Megabytes. In that case, simply
switch legacy plugin to OFF just for the CB 1.2 RC 2 installation, then
you can switch it back to ON if needed. Or add line (similarly as above):
ini_set( 'memory_limit', '16M' ); @ini_set( 'memory_limit', '32M' );
Hope that helps.
Please report back if one of the 2 solutions cured your problem or not.
