When opening the wrapper at http://YourWebServer/YourPath/biocase_nn_wrapper.php I get a CGI Error?
Most of the times this happens if your wrapper cannot connect to your database (NoDIT). Please check if your DSN is a system DSN and accessible. If you still encounter problems, please check the file permissions of the MDB file (right-click NoDIT.mdb, chose properties).
Add user "Everyone" with Full Control.

Everything runs without errors, why does the wrapper not return anything?
First check if your NoDIT database contains records ! For some National Nodes there is no BioCISE data available, so you have to enter data first.

In the first published version of the wrapper, a php-timeout could occur (30sec) if NoDIT contained more than 100 records. Please download the recent version of the wrapper and replace the file 'biocase_nn_wrapper.php' on your server with the new version in the zip archive. All other files like your configuration-file don't need to be changed. If you still cant see anything, check PHP-timeout below.

After waiting for 30 seconds I get an error saying webpage is not available?
Although the wrapper software tries to change your PHP timeout settings, sometimes this is not possible due to security restrictions. Please try to modify your php.ini settings. On a windows machine it can be found at C:/WINNT/PHP.INI
Please change the following line:

;;;;;;;;;;;;;;;;;;;
; Resource Limits ;
;;;;;;;;;;;;;;;;;;;

max_execution_time = 30 ; Maximum execution time of each script, in seconds
memory_limit = 8M ; Maximum amount of memory a script may consume (8MB)

into this line:

;;;;;;;;;;;;;;;;;;;
; Resource Limits ;
;;;;;;;;;;;;;;;;;;;

max_execution_time = 600; Maximum execution time of each script, in seconds
memory_limit = 32M ; Maximum amount of memory a script may consume (8MB)

and restart your webserver.

I successfully installed the NoDIT database and the wrapper. Why are my data not visible on the preliminary data access system?
The software which loads the national node data into the core meta database (CORM) installed in Berlin is running once or twice a day only. Therefore your data will usually be visible on the preliminary data access system (http://www.biocase.org/biocasesimple/default.cfm) a couple of hours after you launched your national node database.

I get an error saying "Fatal error: Cannot redeclare unixdate() in E:\htdocs\nodit\adodb\adodb.inc.php on line 1306" .
On some systems the metawrapper software version <v1.2 had problems with the adodb library used. Please download the latest version of the metawrapper software (1.2+) and replace the old wrapper with the new files.
