Issues on updating from 4.6 version to 7.8

Hello there, I’ve updated the theme from 4.6 to 7.8.
I updated theme, wordpress (4.7.3), visual composer and all plugins.
But the home page is full of errors:

[td_slide_big limit=”12″ category_id=”4″ category_ids=”247, 128, 127, 8, 96, 9″ autoplay=”7″]
[td_block2 limit=”8″ ajax_pagination=”next_prev” category_id=”1″ header_color=”#1e73be” show_child_cat=”all”][td_ad_box spot_id=”custom_ad_1″]
[td_ad_box spot_id=”custom_ad_2″][td_social custom_title=”BE SOCIAL” icon_style=”2″ icon_size=”32″ facebook=”http://www.facebook.com/pages/*********″ googleplus=”https://plus.google.com/********″ instagram=”http://instagram.com/*********” twitter=”http://twitter.com/#!/***********” youtube=”http://www.youtube.com/user/************” header_color=”#0087a3″ open_in_new_window=”y” linkedin=”https://www.linkedin.com/company/********-com”][td_text_with_title custom_title=”APPUNTAMENTI” header_color=”#0087a3″]

Etc.etc…

You can see the home page here:

You might need to redo home page due to so many things changing since 4x to 7x.

You can “try” simply resaving it. That used to work for me. Clear cache, etc.

Is there a way to convert the code for new template version?

I have another big big big issue with Siteground hosting.
I have a cloud server (3 CPU Cores, CentOS, 5GB RAM, 80GB SSD) and a few months I started to have some server down with this error: “503 service temporarily unavailable”. It appear about 1 time per hour approx. In last months I make a lot of changing, suggested by Siteground senior support (installed plugins, restricted bots visits…) They always said me that the issue was on the website where I have installe Newspaper template, and that might need to update it to solve this issue of server crash/down.
Well, after the total update the issue remain…
I think that could be for the big database (285 mb approx).
Do you have some experience with this server issue or some suggestion?
Thank you…

Best solution is to make sure images extremely well optimized, ensure you use opcache with PHP 5.6 or higher (do not use 5.2 or 5.4 .. ooooold!); limit “queries” on each page — such as megamenu images, sidebars, footers, disable XMLRPC, disable track back/ping-backs, etc.

Thank you for your kind reply.
I just use apache with PHP 5.6.
Can you advise me the beste way to limit queries without changing megamenu and disable XMLRPC ?
Is there some plugin to disable track back, ping back…
Thanks a lot.
