Friends; I found 9 errors in the scan I performed with the help of the Validator to see the errors on my site.
For example, it says Line :32 Column: 85. Can you help me find out in which folder/file directory this mentioned path is located?
Control link so you can see it too: http://validator.w3.org/check?uri=http%3A%2F%2Fsifahocasi.com%2F&charset=(detect+automatically)&doctype=Inline&group=0
My site is currently opening in 20 seconds. I need to fix the errors and find out if the problem is caused by me. Thanks to the friends who will help.
bu hataların açılış hızınızı çok etkileyeceğini sanmıyorum.
Olsun ben yine de elimden geldiğince düzelteyim. Suçu sunucuya atmadan kendi suçlarımı düzelteyim 
The errors and warnings there are the line and column numbers on your homepage’s html output. For example;
Line 32, Column 105: Attribute itemprop not allowed on element meta at this point.
Here it says that the itemprop attribute appears inside the meta element. According to my records, this is not appropriate, remove them. What should we understand from this? The meta tag is in the head section of the site. Therefore, if we remove the parts with itemprop in the theme file that makes up the head section, the problem will be solved.
By working through them like this, you can fix almost all of them.
I think a bit of coding knowledge is also needed for this job. When I tried to manually fix these errors myself, I would fix one error, but when I searched again, I would encounter different errors. I fixed the ones I could and just left the rest as they were..
@sifahocasi the link you provided does not show an error on Line 32. Did you make a change and fix it?
By the way, there are other errors. For example, if you look at the screenshot at VPS/VDS сервера в России - купить виртуальный сервер в Москве
it wants a / added to the end of the line. So it should be like the following.
Unclosed tags (i.e., img, br, hr, etc.) should be closed with /> at the end.
