After installing an extension, the frontpage (and all other pages) is blank...???

Hello
i downloaded and installed this:
https://www.opencart.com/index.php?rout ... ded&page=2
Eventhough it was not compatible with my 2.3.0.2 i wanted to try since others (2.0.0.0, 2.0.1.0, 2.0.1.1, 2.0.2.0, 2.0.3.1, 2.1.0.1, 2.1.0.2) extension worked or worst case scenario just did not work, this o ne instead blanked my website.
I deleted all the data in the ftp, check the Extensions ERROR LOG for any anomalies but looks good, i contacted the developer giving him my data...any idea?

In Modification/Log is still there
MOD: Contact_Social
CODE: $data['title'] = $this->document->getTitle();
LINE: 30
CODE: $data['text_newsletter'] = $this->language->get('text_newsletter');
LINE: 27
but i dont know what should i do with this information

The ADMIN panel works without any problems, as well as the FTP

I tried to change the name
/htdocs/system/storage/modification/
to
/htdocs/system/storage/modification2
just to see if without the modfication folder would work(like last time i installed a corrupted extension), nope.

I changed the name of index.php (in my root folder) and it shows the page undercostruction...does it mean that index.php is corrupted?

I've downloaded and examined the extension for you and it contains only these files: So if you remove those and clear your vqcache, that should fully remove the extension and any other issues you see are related to something else.

yeah those files have been deleted, but nothing changed.
What do you mean by clearing "vqcache"? You mean from ADMIN-MODIFICATION-REFRESH/CLEAR?

vQmod is different to OCMOD and the cache isn't cleared in the same way.

You clear it by deleting the files in the vqcache folder, more info here:

i give it a try, if doesnt work....what should i do? uninstall e re-install opencart?

Try it first, if it doesn't work then paste the error message here. If there's a blank screen it means the error message will be in error_log or the OpenCart error log.

SOLVED.... i clear that and ocmod and now it works.
Thx for the help mate
