Én nem beszélek magyarul. A Google Translate, nem értem a megjegyzést. Bocsánat.
Próbáld egyszer?bb magyar.
Ha más nyelven beszél, akkor próbáljon meg angol, francia, spanyol, lengyel vagy.
Angolból fordították a Google Translate.

I don’t speak Hungarian. Using Google Translate, I cannot understand your comment. Sorry.
Try simpler Hungarian.
If you speak other languages, you can try English, French, Spanish, or Polish.

thank you so much..It really helps a lot.

Yes, it is possible to have multiple website installed under xampp.
The key is to put them into different folders under htdocs
For example, let’s suppose you have 3 websites you want to play around with under XAMPP. We’ll call them, “My Cool Website”, “My Awesome Website”, and “My Rockin’ Website”.
You can run all three under XAMPP as long as they are installed in different directories under htdocs. They can even be installed on different platforms (Joomla!, WordPress, Drupal, etc).
To access them in a browser you would type: localhost/<folder name>
Where folder name is the name of the folder you installed to. Please note – avoid spaces in your folder name.
localhost maps to the htdocs folder. Any directories you put in htdocs can be accessed by just appending them to localhost.
You don’t have to stop at one level of directory nesting – you can go deeper.
It is perfectly valid to have something like this: htdocs\website\another_website\still_another
Where you have a website at each subdirectory. You would access each one as follows:
localhost/website
localhost/website/another_website
localhost/website/another_website/still_another
Personally, I wouldn’t do it that way – I would keep all websites at the same level.
THe only time I would create a website under another one is if one part of my website was powered by a different technology.
For example, suppose I ran my main site on WordPress, but in addition to having articles and comments, I want a forum section where people can discuss things. I am sure WordPress has some sort of forum plugin, but I would prefer to go with a standalone application that is specifically design for forums. So I would install it in a subdirectory called forum:

htdocs
------website_1
---------------forum
------website_2

In this case, I have 3 websites installed under htdocs. Two at the same level and one a little deeper.
I hope this answers your question and thanks for asking.
(I apologise that comments need moderation, but I get way too much comment SPAM – even with filters.)

Thanks :)) I thought it was that however was not sure.
Thanks again

The Apache server log is a text file. You can find it in C:\xampp\apache\logs\access.log.
There is a lot of data in it and it is quite raw.
This tool might help with viewing the log. It claims to be free, but I have never used it, so I have no comment on it other than “I found it while googling”.
I hope that answers your question.

The likely problem is a port conlict.
Port 80 and 443 are used by the Apache Server. If you are running Windows, you might has IIS installed and running. Check this tutorial for removing it. IIS is Microsofts version of a http server.
Port 3306 is used by the MySQL database.
If those ports are being used by another application, then Apache Server and MySQL will not run.
Check out this tutorial on trouble shooting port conflicts.

My best guess on why it installed the German version is that Deutsch was selected during installation.
This option is available for XAMPP 1.7.4 and 1.7.7. I can’t see any language option for XAMPP 1.7.3 – English seems to be the only choice.
To change the language from German to English, try the following:
1) Find the heading: Oberfläche
2) Underneath that will be a line and dropdown box with the heading: Sprache – Language
3) Click on the dropdown box and select English (or your language of choice)
Hopefully, that will set your language back to English (or your language of choice).
