When your webpage loads in the editor, you may sometimes encounter issues. These issues could range from the page missing some functionalities to sections missing entirely.
To cater to this, Wingify enables you to self-diagnose and resolve issues without contacting the support team. First, let’s look at some of the potential issues.
Issues You Might Encounter When Loading Your Website in Wingify Visual Editor
Wingify broadly classifies the common issues into the following three categories:
- Editor loaded in Fallback mode: When the editor loads your website in Fallback mode, i.e., over a proxy server, a warning message appears, describing why the editor loaded in Fallback mode and how to fix it.
- Failed to load the page in the Wingify Visual Editor: When the editor fails to load the page, a message is displayed in Wingify. This usually happens when the Wingify SmartCode is missing from the webpage you are trying to edit, and your servers block the page from loading via proxy.
- Other issues: If you don't see any error codes or failure messages and the page still loads with some defects in the editor.
Fallback Mode Errors
If the editor loads in Fallback mode, you may notice any of the following error codes: 0000, 0003, 0010, 0100, 0101, 0102, 0103, 0104, 1000, 1003, 1100, 1101, 1102, 1103, 1104. To view the resolution steps, click the one that pertains to your case.
