For errors that cannot be investigated with a screenshot of your site or the sitebuilder, it may be necessary to open the browser console.
- Go to the page where the error appears and click F12 on your keyboard to open Developer Tools.
- Click the Console tab if it is not already selected. This is the same for both Chrome and Firefox.
- If there appears to be a large amount of code under the Console tab accompanied by a scrollbar, you have the option of enlarging the dock to fullscreen. For Chrome, click the dotted line near the X to expand the "Dock side" option and click the icon for "separate window".
For Firefox, click the "separate window" icon near the X.
