Issue Summary

Clicking on the Source Editor button does not work and throws an error:

The source editor requires Confluence 4.1.5 or greater.

The error pops up regardless of running a recent Confluence version.

Steps to Reproduce

1. Install a recent Confluence version (such as 7.13.4 LTS or latest)
2. Install the Confluence Source Editor App version 2.0.0 (or latest)
3. Hide the version information by executing the steps in How to Hide Version Information on Confluence
4. Restart Confluence
5. Create a new Page (or Edit an existing Page)
6. Click on the Source Editor button (with a "<>" symbol)

Expected Results

Users are able to edit Pages via the Source Editor successfully.

Actual Results

The Source Editor will not work and a pop-up error will be displayed.

Cause

The Source Editor checks compatibility via the "version-number" value:

function isMinimumVersion() {
    var version = Meta.get('version-number');
    var versionParts = version.split('.');
    if (version.indexOf('SNAPSHOT') >= 0) return true; // always allow snapshot at own peril

    var major = parseInt(versionParts.length > 0 && versionParts[0] || 0);
    var minor = parseInt(versionParts.length > 1 && versionParts[1] || 0);
    var patch = parseInt(versionParts.length > 2 && versionParts[2] || 0);
    // Min version = 4.1.5
    if (major > 4) return true;
    if (major === 4 && minor >= 2) return true;
    if (major === 4 && minor === 1 && patch >= 5) return true;

    return false;
}

As it was obfuscated and hard-coded to "1" it will fail the condition every time and return a False regardless of the Confluence version being compatible.

Workaround

Use a value of "99.99" that will both satisfy the condition and also obfuscate the Confluence version - or revert the steps covered under How to Hide Version Information on Confluence.
