Title: Some validation errors Last modified: February 5, 2025 --- # Some validation errors * [spencerp](https://wordpress.org/support/users/spencerp/) * (@spencerp) * [1 year, 4 months ago](https://wordpress.org/support/topic/some-validation-errors/) * I have an old premium custom wordpress theme from years ago… I did a validation error check with it, and I managed to get it down to 11 errors to fix. I added some pictures /photos in posts and I have some errors I’m not sure about. I think the theme is using “strict” for Doctype. When I try using “transitional” I have like 600 errors.. instead of 11. I’m not sure why “sizes”, “srcset”, “figure”,“ target” would be giving errors when it’s default wordpress outputs unless it’s a bug maybe? * Examples below… * Line 174, Column 233: there is no attribute “srcset” * Line 174, Column 754: there is no attribute “sizes” * Line 178, Column 42: element “figure” undefined * Line 215, Column 242: there is no attribute “target” * Line 25, Column 8: required attribute “type” not specified * Line 174, Column 15: there is no attribute “class” * [Validation Link](https://validator.w3.org/check?uri=https%3A%2F%2Fvindictivebastard.com&charset=%28detect+automatically%29&doctype=Inline&group=0&ss=1#line-730) * The page I need help with: _[[log in](https://login.wordpress.org/?redirect_to=https%3A%2F%2Fwordpress.org%2Fsupport%2Ftopic%2Fsome-validation-errors%2F%3Foutput_format%3Dmd&locale=en_US) to see the link]_ Viewing 2 replies - 1 through 2 (of 2 total) * [George Appiah](https://wordpress.org/support/users/gappiah/) * (@gappiah) * [1 year, 4 months ago](https://wordpress.org/support/topic/some-validation-errors/#post-18287393) * > I’m not sure why “sizes”, “srcset”, “figure”, “target” would be giving errors > when it’s default wordpress outputs unless it’s a bug maybe? * You answered yourself with this: * > I think the theme is using “strict” for Doctype.

I like my old theme though, maybe just update it to modern doctype and etc. I could buy a more modern theme, but I like my old custom theme that my site was known for having. I paid 250.00 USD for the theme and hate to abandon it. I’ll see if my buddy can help me with it. Thanks for your reply, you’ve been helpful.
