PHP on different pages

We would need to see the code - on a working link so we have access to the CSS and JS for the site.

Here are the url's:

This is the one that does not work - LangSystems.net
This is the one that works - Mrbreeze.net/test

I've did a compare on the ".css" files and they match.
They are attached
NewCss.css
NewCss.css

Sites are identical.

I am guessing you have a caching issue on the problem site. I do not see the problem shown in your screen shot on either of the links above.

Checked in FF, Chrome and IE - all work fine.

You came up with the same thing I did as far as the code goes.  But why does the menu look different in the 2 screen shots that I posted?  You saw how on "Langsystems.net" the menu buttons became 2 lines but on "mrbreeze.net/test" they didn't.  If it was a caching issue wouldn't they react the same way?

But why does the menu look different in the 2 screen shots that I posted?

I am confused, the screen shots show an issue that is not being replicated when you go to the links - so if the links are working what is the issue?

In order to say why the menu does that I would need to see an instance where it is happening.

It is not the links, they work.  Please look at the screen prints that I sent.  I'm sending them again.
At "langsystems.net" the buttons for "Space Survey", "Walk By Map", "Daily Activity" and "Data Entry" appear on 2 lines.
At "mrbreeze.net/test" these buttons for "Space Survey", "Walk By Map", "Daily Activity" and "Data Entry" appear on 1 line.

Attached are the screen prints.
LSI_Screen.doc  - Screen print from menu @ "Langsystems.net"
LSI_Screen.doc
Mrbreeze_Screen.doc = Screen print from menu @ "Mrbreeze.net/test"
Mrbreeze_Screen.doc

It is not the links, they work

I was referring to the links you posted
http://langsystems.net/Retail/
http://mrbreeze.net/test/
Both of these render the same - no double menu

At "langsystems.net" the buttons for "Space Survey", "Walk By Map", "Daily Activity" and "Data Entry" appear on 2 lines.

Yes, I understood what you are saying but you have been unable to provide us with a working link that demonstrates the problem. All the screen shots show is the problem - but gives us no idea what is causing it because we don't have access to the underlying code. It is like showing us a picture of your car and asking us why it won't go.

The links you provide show the menu working perfectly - in order to diagnose what is happening I need to see a link that shows me the problem - not a screenshot.

Responsive menu would be best. To solve resize breaks, OP should replace space characters with   in button text (Assisted Solution)
