No valid ad dimensions found in 'as.size' meta tag
To pass validation on the Terminus platform, each creative will need a meta tag that declares the creatives dimensions. The meta tag format can also be found in the guides above - <meta name="ad.size" content="width=W,height=H">.
- Its placement can vary based on the program used to create html5 but it will typically be placed with other meta tags.
Bannersnack is the only tool that will automatically install a dimensions meta tag in each creative. The other tools require the meta tag be placed and the values entered.
No html files present at root level
When zipping html5 creatives together, the html file can't be placed within another file or zipped by itself. This will cause the error to appear.
- The following instructions are available in each of the html5 guides - "Zip the .html , .js and images folder together, DO NOT zip the files as a folder underneath a folder, the .html needs to be on the root level of the zip directory. "
Failed to copy asset
This error will appear if there are any extra spaces or characters in the Ad Size Meta Tag.
- Please ensure the meta tag is added exactly as mentioned in each HTML5 article.
<meta name="ad.size" content="width=W,height=H">
Example - <meta name="ad.size" content="width=160,height=600">Examples that will cause an error- adding a space before the word height, adding any other characters:
<meta name="ad.size" content="width=160, height=600">
<meta name="ad.size" content="width=160px, height=600px">
