the most errors in log are "use of uninitialized value". Then there is a "$* is no longer supported" (use of an old version of cgi-lib). An "\\1 better written as $1". And an "odd number of elements in hash assignment".

thanks

The "odd number of elements in hash assignment" indicates a programming error - potentially caused by mishandling of (unexpected formatting) incoming data.

There is a possibility that the incorrectly populated hash may result in incomplete data displayed.

You will need to examine the code and related data - I suggest you run the code under the command line debugger, and isolate the issue.

        There is no time like the present for postponing what you ought to be doing.

Hello,

I've removed the "odd number of elements in hash assignment" as well as all "\1 better written as $1" error messages and the "$* is no longer supported" message. Staying now are only some "Use of uninitialized value" messages after starting the Perl/CGI-application by calling the stating page.

With the next click I can call the error in my originally database. This should print out all existing FAQ independent from which category. It prints until title of FAQ 50 which is shown. Then it seems to hang a time. At last I get the following message:
