 After updating the site to version 6.8, in the validator –
 validator.w3.org, an error appeared – ‘ Error: Bad value
 `speculationrules` for attribute `type` on element `script`: Subtype
 missing.From line 778, column 1; to line 778, column 32`v>↩</div>↩<script
 type="speculationrules">↩{"pre`’

 How can I fix it? I have no errors on my site except this one and it’s
 very frustrating.

 During the previous update I also had an error in the validator related to
 – `contain-intrinsic-size`, I had to solve it myself by adding to the file
 – `functions.php`, the line `add_filter('wp_img_tag_add_auto_sizes',
 '__return_false');` more about this –
