Unable to use any plugin

[alexd0001]

hi,

my googlemaps version is 0.7.2

and in debug mode it comes an error:

Code:

Warning: file_get_contents(/homepages/4/xxxxx/htdocs/GetSimple_3.0/data/other/user.xml) [function.file-get-contents]: failed to open stream: No such file or directory in /homepages/4/xxxxx/htdocs/GetSimple_3.0/admin/inc/basic.php on line 218

Notice: Trying to get property of non-object in /homepages/4/xxxxx/htdocs/GetSimple_3.0/plugins/p01-contact_gs.php on line 69

Warning: Cannot modify header information - headers already sent by (output started at /homepages/4/xxxxx/htdocs/GetSimple_3.0/admin/inc/basic.php:218) in /homepages/4/xxxxx/htdocs/GetSimple_3.0/admin/inc/cookie_functions.php on line 30
Fehler: Headers already sent in /homepages/4/xxxxx/htdocs/GetSimple_3.0/admin/inc/basic.php on line 218 Wenn Sie nicht vom Browser weitergeleitet werden, klicken Sie hier

it says "no file or directory in /homepages/4/xxxxx/htdocs/GetSimple_3.0/admin/inc/basic.php on line 218" - this is for

Code:

function getXML($file) {
    $xml = file_get_contents($file);
    $data = simplexml_load_string($xml, 'SimpleXMLExtended', LIBXML_NOCDATA);
    return $data;
}

where can i repair this?

gruß - alex

EDIT: - Now i removed the plugins "contact" and "multi user management" and only one error in the backend is now all times on all states:

Code:

Warning: call_user_func_array() [function.call-user-func-array]: First argument is expected to be a valid callback, 'sqr_createNavTab' was given in /homepages/4/xxxxx/htdocs/GetSimple_3.0/admin/inc/plugin_functions.php on line 191

in the Frontend or Plugin-Tag in Backend are no more any other error-messages..
it is only for the navigation-tabs of GS-Backend? I think this is not important for the Problem

hey - thx for your help!!

it is solved! It was the exec-php plugin.. ;(
