Publishing Captivate 12 for use on website. No SCORM

Well, the linked document Lilibiri provided, contains 2 errors which are not present in the published Cp12 index.html of my project. I'm not sure what actually causes those errors but fact is, that the project.js in line 5317 and column 19 throws an Uncaught SyntaxError: ' ' string literal contains an unescaped line break.

"This can occur if a line break, i.e., a new line character (`\n`) or carriage return character (`\r`), is added to the string without being properly escaped." (quoted from here.)

The next error: Uncaught TypeError: can't access property "CPProjInit", window.cp is undefined is very likely a consequence of the previous error.

This alle leads to the problem that the <div>:

<div id="app" style="width: 100%; height: 100%"></div>

is empty, no contents whatsoever, which in turn doesn't surprise that "the screen remains blank".

I attach screenshots of the Javascript console and the page source inspector. Please note that the left side represents Lilibiri's blank document, the right side my fully visible document.

Can you check with an FTP Client or any other similar interface the folder/location in question on your server if there is really an index.html available. In this respect under normal circumstances there is no difference between Cp Classic and Cp 12. See the attached screenshot of one of my published projects coming from Cp 12.

But when you are talking about managing "courses using php and MySQL" - is there something that changed the filename from index.html to index.php? Maybe you'll try to link only to the folder/focation without adding /index.html. Most webservers tend to select the right document to start with automatically.
