Hi Frank, thanks for the reply, but the problem is that I have another server installed by another analyst, who no longer works in the company, in another company building and uses the same version 2.1.2. And the "search with various criteria" does not occur errors, as printed in the appendix.
I have already compared the files and permissions of apache and php conf and everything is the same.
As I previously reported in the apache error log the error does not appear, even in debug mode.
