how to correct the syntax? - erlang

Question

I have configured ejabberd with mysql , but after installation I am not able to start ejabberd server due to a syntax error.
%% Modules enabled in all ejabberd virtual hosts.
%%
{modules,
[
%%{mod_adhoc_odbc, []},
%%{mod_announce_odbc, [{access, announce}]}, % requires mod_adhoc

{mod_muc_log_odbc,[]},

{auth_token, "mod_available_post"},

{mod_unavailable_post_odbc, [

%% Replace it with 'none' if you don't want to send such message:

{mod_stats_odbc, []},
{mod_time_odbc, []},
{mod_vcard_odbc, []},
{mod_version_odbc, []}
]}.
%%
And getting the error is,

635: {mod_version_odbc, []}

E(<0.37.0>:ejabberd_config:106) : Problem loading ejabberd config file /etc/ejabberd/ejabberd.cfg approximately in the line 636: syntax error before: ']'
Please help me to fix this issue.Thanks in advanced.

Answer 1

Here is the problem:
%%{mod_muc_odbc, [
%%{host, "conference.#HOST#"},
{access, muc},
{access_create, muc},
{access_persistent, muc},
{access_admin, muc_admin},
{max_users, 500}
]},
You have commented the first line, but not the rest of the mod_muc_odbc config, causing unbalanced parentheses. Either uncomment the first line, or comment out the rest of them as well.
