The homepage says "2014", how can I fix it??

Depends on how your web site was set up and what theme it uses.

Providing the URL and what theme you’re using would make it a lot easier for people to provide an answer.

The URL is this:

https://www.cambridgeshiresteamrally.co.uk/

I’m using the “Twenty Ten” theme… but on most pages it still says “2015”, on the homepage it says “2015”, but on the tab on the homepage it still says “2014”.

How can I make the homepage tab turn into 2015??

How can I make the homepage tab turn into 2015??

On the video? What do you mean “tab”? Droning the same sentences into people won’t help them understand you better.

can you provide a screenshot to point out exactly which of the 2014 from the front page you want to change?

You mean the Browser tab, don’t you?

Your page has this in the head:

<title>Cambridgeshire Steam Rally 2014, Stow-cum-Quy</title>

if this is about the browser title tab, then double-check the settings and entries of your SEO plugin.

I’ve already put a video on there as well… on every single page it still says “2015”, but on the homepage it still says “2014” in the tab as well… so how can I fix it??

When I look at it in Chrome, it still comes up with tabs at the top.

I’m not going to give you a screenshot, because I can’t add it to this message as well.

Every single page still says “2015”, but on all of the tabs all of the pages still say “2015”, but on the homepage in the tab it still says “2014”… so how can I fix it??

You’re using an “All in One SEO” plugin.

As @alchymyth already mentioned:

“if this is about the browser title tab, then double-check the settings and entries of your SEO plugin. ”

So you’ve done that? Examined the title entry in your SEO plugin settings to see if it says “2014”?

[edit] .. you should also consider updating your version of WordPress.

I do have the “All In One SEO Pack” plugin on the web site too, but how can I change it from “2014” to “2015”??

Examine the title entry in your SEO plugin settings
Does it say 2014? If so, change it to 2015.

It still says “2014” in the home page tab, but I’ve now gone to “All in One SEO” > “General Settings” – I’ve now gone to the “Home Title:” and now modified it! ??
