I quoted what you’d posted back at you. I’ll strip it even further:

call this function in template file to show slideshow as_tejus_show_slideshow(); OR use this shortcode [as_tejus_slides] in posts or pages.

You should have posted all the above at pastebin.com and provided the link.

If you look at what you posted, you’ll find this:

<div class="wholeform">
<h4> call this function in template file to show slideshow as_tejus_show_slideshow();</h4>

<h4>OR use this shortcode [as_tejus_slides] in posts or pages.</h4>
</div>

Looks like a slider plugin was removed or deactivated but there’s still a reference to it in your theme’s index.php. Open the file in a text editor and remove the reference, or re-install/reactivate the slider.

Did you regenerate your thumbnails after setting new image sizes. If not, maybe try doing so using something like:

https://wordpress.org/plugins/force-regenerate-thumbnails/

Why on earth have you posted a WordPress core file that we all have access to anyway?

Those “errors” you’ve posted aren’t errors at all, they’re notices. They’re telling you that some of plugins are using deprecated code, but nevertheless, for now, still work. Notices shouldn’t really spill out on the front end of a live site anyway, they’re meant for developers and should be turned off in a production environment.

Try disabling those named plugins and see if things improve.

You need to check the contents of your wp-config.php file and make sure the database details match those of your site.

When you go to Screen Options, re-check comments. Once done, on the page or post edit screen, scroll down and you can then un-check comments.

Checked screen options merely display the comment options on a post or page edit screen.

If you have a copy of the directory containing WordPress + themes/plugins etc, then yes, you should be able to eventually recreate the site. You won’t be able to recover any content however unless you have a copy of the associated database.
