Hi out there,
hope to find some help and the topic is written good enough, that the next one with the same problem will find it easier and can fix it. I looked around, but found nothing like this. Well and...erm...I don't have any idea about making programs by myself ^^


[b]Following Problem.[/b] 

I asked my Host to activate "mod_rewrite" for me. I wanted this, because i want to have SEF activated on my site.
So since they have activated it, i have some problems.

Currently the following config is working on the server:

MySQL: 5.0.67-0.dotdeb.1
PHP: 5.2.6-0.dotdeb.1
memorylimit is on 40MB
htaccess:
[code]
AddHandler x-httpd-php5 .php
AddType application/x-httpd-php5 .php

# The line just below this section: 'Options +FollowSymLinks' may cause problems
# with some server configurations.  It is required for use of mod_rewrite, but may already
# be set by your server administrator in a way that dissallows changing it in
# your .htaccess file.  If using it causes your server to error out, comment it out (add # to
# beginning of line), reload your site in your browser and test your sef url's.  If they work,
# it has been set by your server administrator and you do not need it set here.

3 Sites are working on the Host.
[b]Mainsite:[/b] [url]http://www.bruderschaft24.de[/url]
Everything here is working fine here, cb is NOT installed at this site.

[b]second site: [/b][url]http://www.bruderschaft-metin2.de[/url]

cb 1.2 RC3 is installed and was working fine till yesterday after the activation.

Following Mistakes before using login (path changed!):
[b]Fatal error: Allowed memory size of 16777216 bytes exhausted (tried to allocate 232 bytes) in /var/.../.../html/joomla/components/com_comprofiler/plugin/user/plug_cbcore/cb.core.php on line 2007[/b]

This includes the following code (cb.core.php):

[code]	/**
	 * Prepares field data for saving to database (safe transfer from $postdata to $user)
	 * Override
	 *
	 * @param  moscomprofilerFields  $field
	 * @param  moscomprofilerUser    $user      RETURNED populated: touch only variables related to saving this field (also when not validating for showing re-edit)
	 * @param  array                 $postdata  Typically $_POST (but not necessarily), filtering required.
	 * @param  string                $reason    'profile' for save user edit, 'register' for save registration
	 * @return boolean                          True: All fields have validated, False: Some fields didn't validate
	 */
	function prepareFieldDataSave( &$field, &$user, &$postdata, $reason ) {
		$this->_prepareFieldMetaSave( $field, $user, $postdata, $reason );

		foreach ( $field->getTableColumns() as $col ) {
			$value						=	stripslashes( cbGetParam( $postdata, $col, '' ) );
			$valueText					=	stripslashes( cbGetParam( $postdata, $col . 'Text', '' ) );

			if ( $value !== null ) {
				$value					=	str_replace( array( 'mailto:', 'http://', 'https://' ), '', $value );
	
				if ( $valueText ) {
					$oValuesArr			=	array();
					$oValuesArr[0]		=	$value;
					$oValuesArr[1]		=	str_replace( array( 'mailto:', 'http://', 'https://' ),'', $valueText );
					$value				=	$this->_implodeCBvalues( $oValuesArr );
				}
			}
			$this->validate( $field, $user, $col, $value, $postdata, $reason );
			if ( $value !== null ) {
				$user->$col				=	$value;
			}
		}
		return true;
	}[/code]
Line 2007 is the line [b]after[/b] the last semicolon (;)

I activated the maintenance mode in joomla, so i could login. 
But I also get an Errorpage:
[b]Fatal error: Allowed memory size of 16777216 bytes exhausted (tried to allocate 1024 bytes) in /var/.../.../html/joomla/components/com_comprofiler/plugin/user/plug_cbcore/cb.core.php on line 1113[/b]

[code]	function _intToSql( &$field, $col, $value, $operator, $searchMode ) {
		$value							=	(int) $value;
		// $this->validate( $field, $user, $col, $value, $postdata, $reason );
		$sql							=	new cbSqlQueryPart();
		$sql->tag						=	'column';
		$sql->name						=	$col;
		$sql->table						=	$field->table;
		$sql->type						=	'sql:field';
		$sql->operator					=	$operator;
		$sql->value						=	$value;
		$sql->valuetype					=	'const:int';
		$sql->searchmode				=	$searchMode;
		return $sql;
	}
}[/code]

The last line is line 1113.

[b]third site:[/b] [url]http://pirates.bruderschaft24.de[/url]

This site has the same problem like the second one. Only on different lines.
[b]
Why do I think, it is a problem from the cb_login_module?[/b]

Because i deactivated it. Everything workes fine, the page looks like every day. You can just not log in anymore.

[b]Any ideas???[/b]
