DCG Error Message 4
Page Source message
DCG Error Message 4: DCG Metabox Image URL is empty and Default Image does not exist.
Rating: Non-critical. This error does not prevent the gallery from working properly.
Fix: Enter an image URL in the DCG Metabox Image URL field for this Page/Post and/or define a Default Image in the DCG Settings page.Can I ignore it?
Not if you want a good-looking gallery. It's a non-critical error and won't stop the gallery working, but you will see the plugin's "Error" image instead of a proper image. In other words, you should fix it.
How do I fix it?
This error is triggered because the DCG Metabox Image URL field for the relevant Post/Page is empty, AND your Default Image cannot be found. To fix this, do the following:
- Enter a suitable Image URL in the Write Post/Page DCG Metabox for the relevant Post/Page.
This error message also means that you either haven't set up your Default Images properly, or you have, but the Default Image can't be found at its expected location on your server. For the former:
- If you're using the Multi Option or One Category Gallery Methods, check that the URL to your Default Images folder is correct in the Settings Page, and that you have named the Default Images correctly, and uploaded them to the folder you have specifed in the Settings Page.
- If you're using the Pages Gallery Method, check that the URL to your Default Image (there can only be one default image when using Pages) is correct and that your specified file is located at that URL.
Note for WPMU users
Default Images are not available when the DCG is used with WPMU. Just follow this step to clear the error:
- Enter a suitable Image URL in the Write Post/Page DCG Metabox for the relevant Post/Page.
Documentation and Configuration resources
See Docs - How to assign an image and a description to each Post/Page
See Docs - How to name and organise your default imagesOther info
Note: this error is always accompanied by the display of the plugin's "Error" image for the Post/Page with the missing image. However, this error is NOT triggered in the event you have entered a Image URL in the DCG Metabox and this image can't be found. If you see a black loading bar instead of the plugin's "Error" image (and all other images are displaying fine), it means that there is a URL in the DCG Metabox Image URL field but the URL entered here is wrong. Check the Image URL you have entered in the DCG Metabox.
