Hello,

I don't know what is the issue. You need to find it. Was it working before? Did you restore the database in new server? Did you update the config on new server?

The `base_url` in the `app/config/config.php` and database settings in `app/config/database.php`

Please check those along with your server error logs.

Thank you

base_url and database settings are OK, Now I update the system using update tool, now I can login but after the login everything going blank, what is this issue ? how to fix ?

Please check the server error logs for 500 error details and let me know so that I can suggest. Thank you

Is this the error log ?

No. These are access logs. If you are not sure, you can check with your server admin/host.

Hey... if I give you a ftp can you fix this issue ?

Hello,

I am sorry but the service to check installation/server is not free. You can [open ticket](/support/tickets/new) for `Check server/installation for me ($10)` and provide your server details. We can't fix any server issues but will update you what need to be changed.

Thank you

OK, Can you please give me a link to download Simple Invoice Manager 3.4.5.1 ?
if you can do this help, I'm really appreciate.

I am sorry as we can't save many versions only last 4 - 5 only. I checked the tag was started after 3.6.0 so I don't have version below.

I don't recommend you to use old versions, please always use the latest version.

Did you check the server error logs? I am not sure if app logs can help but you can enable app logs by changing the `log_threshold` to 1 in `app/config/config.php` and then visit the page again to produce error. Lastly check the latest error logs in `app/logs/` folder. This could be helpful to know if the app generating any errors.

Thank you
