As of today, when I'm accessing my website it comes up an error below:

A PHP Error was encountered

Severity: Notice

Message: Only variable references should be returned by reference

Filename: core/Common.php

Line Number: 257

A PHP Error was encountered

Severity: Warning

Message: Cannot modify header information - headers already sent by (output started at /home/hbtlaw/public_html/system/core/Exceptions.php:185)

Filename: libraries/Session.php

Line Number: 675

A PHP Error was encountered

Severity: Warning

Message: Cannot modify header information - headers already sent by (output started at /home/hbtlaw/public_html/system/core/Exceptions.php:185)

Filename: core/Common.php

Line Number: 438

I have tried the solution on below link but it still doesn't work

Get errors when accessing admin panel

Only variable references should be returned by reference - Codeigniter

By changing

Edit filename: core/Common.php, line number: 257

Before

return $_config[0] =& $config;

After

$_config[0] =& $config; return $_config[0];

Please advice if someone ever experience the issue like I had.

Thank you so much.

Message: Cannot modify header information - headers already sent by...

This error pop when you try to send some header information to the browser but headers are already sent. In your case it's probably because of your variable issue. Don't try to fix the header error. What you need to do is, just create the correct flow of data and i will automatically fix. We can help you with that if you can show us the functions that course the issue.
