TYPO3 Core

I think the memory limit is still too low. Try setting it to 50M (just to be sure that this is not the problem) and check if it's working.

Limit was set to 50M, but still missing any output from the server.
I set the error_reporting to E_ALL, but I can't see any error.

Am having the same problem.

Memory limit set to 50Mb

I have commented out //$SOBE->main(); in the ../typo3/mod/tools/em/index.php

Still blank.

Redhat 9
PHP_VERSION : 4.2.2
MySQL - 3.23.54
Apache/2.0.40

I'm install TYPO3 4.0.3
All work fine but when i click at left frame "Ext Manager", say "The page cannot be shown".

Another thing: Although i had install the TYPO3 4.0.3 version the BE page show "TYPO3 4.0.2 Web Content Management System" ¿Why?

Here also the same thing happens. I tried 4.0.1 and 4.0.2 but problem is that EM not shown. In debian gnu/linux 3.1 there is no such problem.

Look at bug report
http://bugs.typo3.org/view.php?id=2615

Similiar problem. Try the latest patch and run the install tool to make necessary database updates.

Tennyson: You have to use the update function in the installtool to upgrade too 4.0.3

Same problem with typo 4.0.4 on a
RedHat 7.3 system

Php-version: 4.1.2-7.3.6
apache: 1.3.27-2
mysql: 3.23.49-3

I've tried the mentioned patch (also updated the db) but it does not solve the problem. Also different memory limits don't show any success.

I have also commented out //$SOBE->main(); in the ../typo3/mod/tools/em/index.php -> still blank.

I have the same problem running on 4.0.4.. The extension manager shows up, but I can't see any extensions exept the loaded ones..

search retrieves no results...

I guess for now I have to get extensions "manually" and upload them to my server.

I've fixed my problem:
it results from the php version and the function

if(version_compare($versionRange⁰,'3....

in the class.em_index.php in the function fixMEMCONF.
The issue can be solved by upgrading php or modifying the lines containing version_compare like this:

if(empty($versionRange¹)) {
$versionRange¹ = '';
}else {
if(version_compare($versionRange¹,'3.0.0','<')) $versionRange¹ = '';
}
