Preview a page in your Browser
Select File->Preview in Browser->Default Browser (F5) to preview the current page in your default browser. It's also possible to change the browser that is used for previewing. Go to File->Preview in Browser->Edit Browser List to add/edit the list of browsers that can be used to preview the pages you are working on.
Depending on the preview scope (Tools->Options->Publish & Preview), you can either preview a single page or the entire web site.
Internal links do not work in Preview, unless you have set the Preview Scope to Entire Web Site!
If you only preview a single page, your browser will not be able to find all the other (internal) pages unless you also generate them!
You cannot preview pages with PHP in your browser. They can only be viewed on a webserver with PHP support!
However you can remove PHP code for preview by enabling 'Remove PHP during preview' in Tools->Options->Publish & Preview.
Default browser configuration
The default browser is a system setting. This is not specific to WYSIWYG Web Builder!
You can change the default web browser in the Windows Control Panel.
What to do when preview doesn't work with your default browser?
Some users have accidently assigned the wrong application to the HTML file type. In that case Windows will display the HTML page in another application. Follow these steps to correct this:
In the Windows Control Panel click 'Set Default Programs'. Select your default browser and then Choose defaults for this program.
Select .htm and .html and click Save.
If this still doesn't work then there may be another problem with your system. In that case we recommend to use a system repair tool like CCleaner or Fix-It Utilities to repair file associations.
