Error in Exporting Test suites

[sss]

Hi,

I am new to Testlink and we are trying to use TestLink 1.8.3 version. We are facing some issue , when we are trying to export the test suites. The error displayed is


ERROR ON exec_query() - database.class.php

I have created the test project->test suite which has few child test suites. The child test suites has the test cases in it. If i export individual test cases it is working fine, but exporting whole test suites i am getting this error. The user has admin permission.

Browser version used is Firefox 3.0.17. Any help is appreciated.

Thanks

Just now we have upgraded the version to 1.8.5 and its giving error as

Fatal error: Call to undefined function reportfatal() in C:\xampp\htdocs\testlink\lib\functions\database.class.php on line 193

Looks like the exported file has some limit , if i am exporting upto 26 test cases which amount to 20.7 KB ( As i m seeing in download rate) it is working fine. But above if i add, even one test case it is resulting in the above mentioned error.

Please help me in analysing and solving the problem. Is something to do with database, do we have to configure somewhere the limit?

Thanks

In config.in.php i could find limit on importing file sizes

$tlCfg->import_max_size = '409600'; // in bytes

/** Maximum line size of the imported file */
$tlCfg->import_max_row = '10000'; // in chars

but no reference to exporting file size.
