The theme has developed multiple issues (Load time, CSS, Category error etc.)

Have you tried:

– switching to the Twenty Eleven theme to rule out any theme-specific problems.

– resetting the plugins folder by FTP or PhpMyAdmin. Sometimes, an apparently inactive plugin can still cause problems.

I wanted to add that the same theme had been serving us well for over a year and a half and no such issue occurred.
Can it possibly be a fatal error in coding? The question is how to detect what is causing the problem.

Thanks for your input esmi!

I do not think Plugins are to blame. I have limited number of pluggins on the website and are being used for several months. And I have no idea how to switch to Twenty Eleven theme. Let me look around for similar thread.

The problem was occurring due to a faulty code in the header. I deleted it and the garbage codes are gone. But the site is still very slow.
Can any of you shed light on that?

Loaded fine for me on that page, but you have many mark-up errors:

https://validator.w3.org/check?uri=http%3A%2F%2Fwww.successstories.co.in%2Farchives-2%2F&charset=%28detect+automatically%29&doctype=Inline&group=0

The front page has over 250 warnings?
So I have to bring them to ‘0’?
Or the WordPress themes do contain such warnings?

Some errors (and warnings) are not a big problem, but missing or stray or extra or unclosed tags are a problem. Duplicate IDs too. Google also does not like invalid code, so it’s to your advantage to clean those kinds of things up.

Yes, some themes do have coding errors in them – partly because some “errors” are not really mistakes but a result of changing coding standards or browser inconsistencies.

Thanks Yogi!

I have asked my wife to try and fix ’em all.

LOL! That’s true love! But the real question is what are you doing for her? (Maybe you should not answer that here — ha ha!)

It is her website and her theme. As a responsible husband, I’m doing all I can..social media and the stuffs like that. The blog gets about 3k to 5k pageview per day so she is doing good ??

Ah okay…so you’re really the good guy here – sweet. Sounds like you’re both doing good!

FYI, many of the errors are likely in her content…it’s pretty easy to track those down using the validator results line numbers and Firebug and View Source of the rendered HTML code.

My 3 year old son is listening to John Mayor’s Free Falling so she has got time to look into them one by one. She is saying that some warnings and errors are so confusing.
I will keep the thread open and hope you will stay in touch.

Thanks,
Alex

She is unable to understand some of them. For example the following:
Line 210, Column 142: cannot generate system identifier for general entity “h”
…tent/uploads/2012/11/Garrett-Camp.jpg&h=90&w=90&zc=1" class="teaser_img" alt="…

She checked the first page of the blog:
https://www.ads-software.com/support/topic/the-theme-has-developed-multiple-issues-load-time-css-category-error-etc?replies=13#post-3482192

images are properly defined and are opening well, then why are they showing as warning?

Hi Esmi and Yogi!
She has worked on the validator and now the warning is showing to ‘0’ earlier, it was showing 263. https://validator.w3.org/check?uri=http%3A%2F%2Fwww.successstories.co.in%2F&charset=%28detect+automatically%29&doctype=Inline&group=0&user-agent=W3C_Validator%2F1.3

The real problem still remains the same…The site is still very slow.

What else should be done?
