Hello!! I am from Argentina. I installed koha in a red hat enterprise linux 5, with all the necessary perl modules and pre-requisites. But when i run it, i received the following error:"Koha Error production mode - trapped fatal error" . After 5 days looking for the solution, i do not know how to fix it. Here is the log error in the koha-error_log. Please help me.Thank you very much. Diego A.
