5762The solution is to configure PHP to link against the real MySQL libraries
5763 and recompile mod_php.
5764 Apache will run properly once the modules are all using the same version
5765 of the MySQL libraries.

5773Apache appears to start up fine, but nothing is getting logged in the database
5774\layout Standard
5775
5776If you do not see any entries in the access_log, then something is preventing
5777 the inserts from happening.
5778 This could be caused by several things:
5779\layout Itemize
5780
5781Improper privileges set up in the MySQL database
5782\layout Itemize
5783
5784You aren't hitting a VirtualHost that has a LogSQLTransferLogTable entry
5785
5786\layout Itemize
5787
5788You didn't specify the right database host or login information
5789\layout Itemize
5790
5791Another factor is preventing a connection to the database
5792\layout Standard
5793
5794Important: it is improper to ask for help before you have followed these
5795 steps.
5796\layout Standard
5797
5798First examine the MySQL log that you established in step

5801\end_inset

5803 of section

5805
5806\end_inset
5807
5808.
5809 Ensure that the INSERT statements are not being rejected because of a malformed
5810 table name or other typographical error.
5811 By enabling that log, you instructed MySQL to log every connection and
5812 command it receives -- if you see no INSERT attempts in the log, the module
5813 isn't successfully connecting to the database.
5814 If you see nothing at all in the log -- not even a record of your administrativ
5815e connection attempts, then you did not enable the log correctly.
5816 If you do see INSERT attempts but they are failing, the log should tell
5817 you why.
5818\layout Standard
5819
5820Second, confirm that your

5826
5827Third, examine the Apache

5832 to why it cannot connect, etc.
5833
5834\layout Standard
5835
5836The next thing to do is recompile the module with debugging output activated.
5837 change the "#undef DEBUG" on line 8 of mod_log_sql.c to "#define DEBUG"
5838 and recompile/reinstall.
5839 The module will now output copious notes about what it is doing, and this
5840 will help you (and the maintainer) solve the problem.
5841 In order to see the debugging messages, ensure that you make them visible
