    I needed to change the default height of the Homepage slideshow and set it from height 340px to 500px.

    Browsing through the Forum I found Dude’s repeating advice:

    “You can change the slideshow/image dimensions in functions.php (I’d only adjust the height value). Afterwards regenerate the thumbnails with:

    I did exactly these steps and yesterday evening it was all ok, the slideshow and the images were 500px, no problems.

    Opening my pc this morning I found my site a total mess.

    It totally seems that CSS has crashed.

    I’ve spent a serious amount of time this morning having a chat with the hosting company, saying that the most probable reason for the crash of the site is my editing on functions.php.

    I disagreed with them by arguing that if that was the reason, shouldn’t the problem appear as soon as I hit the update button and not the next morning?

    They gave me a ticket to investigate my issue in more depth and will inform me in the next 24 hours.

    So my question here is the exact same as above?

    Can the editing of the functions.php cause a problem like the one you can see on my site? and can this problem appear next morning and not right away?

    Thanks a lot in advance!


    Hi Bill,

    No, editing that single line in the functions.php should not have caused this. You can test this by downloading the theme from themeforest again and uploading the original functions.php file to your server.

    You might want to try turning of Total Cache and any other plugins you have running. See if that brings the site back to normal.


    I did deactivate all of the plug-ins one by one while making a strong refresh to the page after each deactivation; that fixed partially the problem without fully restoring the site back to its previous look.

    Because mainly I thought it must have been a CSS problem, due to the fact that the search bar was completely destroyed, the navigation bar’s position was off and the bg color of the container was actually replaced by the footer bg assigned color; while all the elements still remained functional,

    (you can see the correct and the problematic screenshots of the site here:

    & the URL of the site is:

    the thing I did was upload the original style.css file, and that finally seemed to fix the problem.

    First question

    My first question though is, how this failure of the CSS could happen, and how this issue manifested itself the next morning?!

    I really don’t want to be in that position when the site finally airs.

    The hosting company said that “WordPress and its components are sometimes updated automatically. That may have been the case here.” Is that really the case?

    Second question

    The second question is regarding the Cache Plug-ins; they seem to cause all this kinds of problems, resulting in being a major problem rather than offering the solutions they are claiming to offer.

    Is it really a need to have a Cache Plug-in and if yes which is the best in your opinion?

    Thanx a lot in advance!


    WordPress never updates anything automatically without your permission.

    As for the Cache-plugins, they can be good but its up to you if you feel its worth it. I’ve used them on sites and never had any issues but I have not tested them with ecommerce plugins.

    Just make sure to keep track of any changes you make to the theme files and keep backups. If you are doing CSS changes, always put them in the custom.css file or in the Quick CSS within the theme admin. That’ll keep your changes even through updates.

    I’ll mark this as resolved, let us know if you need anything else.
