Hello, I use WordPress multisite on my site. (Turkish and english site) I added the hreflang code for Turkish into the head codes of the main site (i also added a hreflang x-default for English?) I just got mail from google saying: Error in hreflang tags at : Mysite We've found hreflang tags on your site, but a few of them have technical issues. Take a look at your hreflang reports to see which hreflang tags have problems. Your website can not benefit from additional language or territory targeting without correcting these tag errors. The search console errors are as follows: URLs and alternative URLs in the "tr" language that are not return tags for your site. Source URL Browsing Date Alternate URL 1 / contact / 08.04.2017 TR.MYSITE 2 / profile / courses / 08.04.2017 TR.MYSITE (I also get the same issue for the tr site. Same mail for there too and there are links to the English site) How can I help you solve it?
