So, I was trying to make an include in the file, and suddenly it triggered a tooltip at the top of my jsp page, the tooltip was in the <html> . I hang over it, and it gives me all sorts of options for setting up a project by default. Here is a snippet of tips:
Change default project: XHTML5
Change default project: XHTML 1.0 Strict
Change default project: XHTML 1.0 Transitional
Change default project: XHTML 1.0 Frameset
Change default project: XHTML 1.1
Being a fool, I accidentally clicked on one of them. As for the fact that I'm not sure, but now he made every HTML file in it have errors or warnings and say that my HTML classes cannot be found from the main CSS file. I tried to check the new version from my repository, but this did not fix it. Errors still exist. I guess this has something to do with Netbeans. I am currently running version 8.2. The project is a web application.
The prompt / error says:
Unable to determine version of XHTML code. You can set a default value for this project.
I always had the same URL in my HTML tag, as I remember and never had any problems. I just tried deleting it, and a tip suggested setting the default HTML project. I set the default value for HTML5, but my classes for my tags are still not found.
Update: removed the XHTML URL in my HTML tag and resolved the problem with HTML errors
I still have a problem with my classes from the main CSS file found, currently all my stylesheets are associated with a single file, which is included on every page on my website. Therefore, there should be no problems finding them, I always did this, and it worked for months.
This is how I link my CSS on the MetaHeader page:
<link href="css/style.css" rel="stylesheet" type="text/css" />
