it will be nice if you can add an image of error or more details about the log

Sure I will give you the image

I have set the image in question

Please provide the complete traceback in the log, not only a screenshot which does not provide the most important information. Also provide information about your installation method and your operating system and use a meaningful title, which relates to the error message. When using the the official installation directives, this should not happen.

Hello @Ermin Trevisan

I am very disappointed that without understanding much, you have closed my question. Its not good. First of all, I am not saying that its fault of odoo. and I have not provide the details of installation because I am installing it in local and I think it may common issue that comes to some people so that I can get the quick answer. If I am doing it on server and got some major issue, I am definitely mentioned all the things.

If you can not got any proper information, I think you should tell me that provide some more information rather then close my question.

Here is the full log
