    Very slow page loading

    Resolved

    Hello,

    I’ve problem with very slow page loading in my website “dentalmonitor.com”.

    Here a screenshot with a speed tool tester:

    I’m pretty sure the problem comes from Forstron’s template, how can I solve?

    Thanks.

    Hi cg_youkey,

    I’m sorry, but from the image there is no clue the issue is caused by the theme. How did you traced the issue to the theme? Have you traced it to a specific script the theme uses?

    From the image provided there if huge delay in first 2 items. First one should be DNS lookup and connection related. I’m not sure what is the second one, but you should be able to check that in the tool you have used for producing the speed test (image).

    They both seems to be related to slow hosting I guess. Have you contacted your hosting company for providing tips on improving the speed of your website? Please note that shared, low cost hosting will be slow nonetheless. Most of website speed problems are actually caused by slow hosting (I have experiences with that…). I personally recommend SiteGround now.

    Please read speed website speed optimization tips in theme documentation at https://webmandesign.github.io/docs/forstron/#speed

    Also, make sure your server run PHP 7 (and newer) as it will boost your site performance significantly.

    Actually, your website loads pretty fast for me. Maybe the initial website lookup is a bit longer (which confirms your image and my advice above). I’m located in Europe, so maybe your hosting company servers are close to my geographical location. Please check with your hosting company where are their servers located and make sure your website is hosted on a server as close as possible to your geographical location. SiteGround hosting actually lets you choose which server you want to use.

    Hi cg_youkey,

    Well, this “only” points out to your whole WordPress installation including plugins and themes :) There is not much of a specific info here.

    I’d start disabling plugins first. Then check your website performance again. If it improves, you know the issue is in some plugin.

    Forstron is a simple theme as it offloads functionality to plugins as you can see. Surely, when you switch to even simpler theme (such as WordPress native TwentySeventeen, for example), you will see some improvement. But this shouldn’t be significant. But you can test to see for yourself.

    If your business is world wide I would strongly suggest using a CDN, such as CloudFlare. Surely, a caching plugin would be a good idea too, I recommend WP Rocket. Other than that you might try some tools such as https://wordpress.org/plugins/p3-profiler/ to determine the bottleneck.

    However, as you can see on my theme demo website, I don’t experience such issues, although I have some 30 active plugins there:

    Thanks Oliver.
    Following your suggestion we have purchased a hosting profile on SiteGround and we have required to move the site.

    They say that the following file are infected by malwares. Can you help us? Do you have suggestion, please?

    [STR]wp_vcd_malware [27/11/17] /wp-includes/wp-vcd.php
    [STR]wp_vcd_malware [27/11/17] /wp-includes/post.php
    [STR]wp_vcd_malware [27/11/17] /wp-content/themes/forstron/functions.php

    Hi cg_youkey,

    If your website was infected by malware, please note that you need to remove it from all affected files.

    You may have been affected by various channels and ways, but I can assure you the theme does not contain any malicious code and passes WordPress code check reviews http://themecheck.org/?q=forstron. Of course, this is only true if you obtained the theme via official chanels: currently only ThemeForest.

    You can test your website files with plugins such as:

    If you are not confident doing this yourself, you can use a dedicated service such as https://sucuri.net/website-security-platform/help-now

    However, cleaning affected files may not be that difficult. I would start by checking the affected files list and comparing them with original, unaffected files. In case of WordPress native files you can download a new copy of WordPress ZIP package and compare with the files inside. In case of Forstron theme, please download the theme ZIP package from ThemeForest and compare files from that ZIP package. If you are using Windows computer, you can use http://winmerge.org software for comparing files (I’m sorry, but I don’t know about Mac alternative).

    Then, if you are lucky, the malware consists of the same code, so you can just batch remove (replace with empty string) the code using a code editor such as Sublime Text.
    If the malware code is different in each affected file, you will need to clean all affected files manually.

    Then your website should be clean.

    A tip: In case of WordPress native files you can simply use newly downloaded ones and don’t bother cleaning those. Basically, all you need to do is to check files within your wp-content folder then.

    Hope this will help.

    Also, you can read some tips about website security in theme documentation.
    And, if you want to stay clean from infections, I strongly suggest using one of the plugins above, or you can also try https://wordpress.org/plugins/better-wp-security/ but that plugin does not have immediate file scanner you can run, it only sends you emails when it detects some file changes.
    When I think about this, your issues with slow website could be caused by malware too, actually.

    And here is some info I’ve found about the malware: https://medium.com/@cirku17/wp-vcd-malware-analysis-7c5dbaad89c3
