Intermittent site loading problems

  • This site has been having intermittent loading/layout problems for several weeks now. Everything is up-to-date back end wise, and I’ve excluded the problem being any theme or plugin (be renaming plugins folder, trying a default theme – problem still exists).

    Sometimes the site is fine in Chrome and Firefox, but then I’ll see that it doesn’t work in IE or Edge. Sometimes it’s not working in Chrome or Firefox. Meantime it will be working on a mobile device. So the problem is quite random really.

    I’ve asked the hosting company for help and they can’t see any server side problems. This is the only site on the server that seems to be experiencing these problems.

    I’ve also reinstalled WordPress, but no change. Today the site is working in Chrome and FF, but intermittently not in Edge or IE. Here is a screenshot of what it looks like in IE this morning. When it’s not working in Chrome and FF it looks similar.

    I asked a developer for help and they said…

    ======

    I’d guess at something to do with permissions or a dodgy htaccess file.

    Particularly weird is if i try to access a single file that should be no problem to view such as a css file i end up with the WordPress 404 page.

    Actually something to check might be case sensitivity – not sure why it would be intermittent though.But when you build on Windows filename case doesn’t matter.

    If you link to style.css in your html, the actual file could be saved as Style.css, STYLE.CSS, sTyLe.CsS and Windows will work fine.

    But Linux filenames are case sensitive, so Style.css, STYLE.CSS, sTyLe.CsS would be treated as 3 different files.

    ===

    Does anybody have any ideas please as to what I can check? .htaccess appears to be okay, but what permissions can I check? Short of rebuilding the site I don’t know what else to do.

    Thanks.

    I see a LOT of 404 errors. For example, the logo is missing:

    https://woodlandtreasures.co.uk/wp-content/uploads/2015/09/logo-woodland-treasures.png returns a 404. Is that file actually on your server? It seems so, because if I try to get just that file, I get it:

    I think there’s an issue with your server — either it’s overloaded or misconfigured.

    Thanks, @sterndata.

    Yes, the logo is here:

    https://woodlandtreasures.co.uk/wp-content/uploads/2015/09/logo-woodland-treasures.png

    I need to talk to the hosting company again then… but it shouldn’t be overloaded, so must be misconfigured. Do you have any idea in what way that could be? If so, why wouldn’t it affect other sites on the same server?

    @sterndata the hosting co say the server is not stressed in any way and they have advised me to set up an account with nodequuery.com, which I’ve just done.

    They also said to make sure that I have the PHP settings set correctly. I think they mean the version of PHP, but the site misbehaves in any versions (it’s now on 7.4).

    Your site loaded quickly and completely for me just now.

    It does not look like you’re using any caching or optimization plugins. I like the combination of Autoptimize and Comet Cache. Give them a try.

    @sterndata so think installing these two plugins will help with the loading problems?

    I think they’ll speed up your site a bit.
