Hi everyone,

[b][b]recently i show error in bottom page said : [/b][/b]

Code:

A PHP Error was encountered

Severity: Core Warning

Message: Module 'timezonedb' already loaded

Filename: Unknown

Line Number: 0

Backtrace:

i search for module timezonedb in php.ini and in .htaccess files i don't find any duplication for loading this module.
could someone help me to fix this error.

thanks

Sounds like timezonedb is being loaded twice in your php.ini.

Are you sure you are looking in and editing the right php.ini? perhaps create a php page with just phpinfo() in it, visit that to view all the details about your php setup - it will show you where php is loading php.ini from, there could be multiple locations, it will be in one of these.

I couldn't change any of our host's php.ini configuration so I prevent the error from appearing by adding an IF statement to the error views:

application/views/errors/html/error_php.php

Code:

<? if($message !== "Module 'timezonedb' already loaded"): ?>
<div style="border:1px solid #990000;padding-left:20px;margin:0 0 10px 0;">
