Magento 2 Error While Installing Tawk.to extension

[FlamyTech]

@Tom Robertshaw, I'm sorry to keep bothering you with this issue, but there's a flicker of success now. Someone on Stack Exchange recommended that I ran the following commands:

    php bin/magento setup:upgrade php bin/magento

    setup:static-content:deploy php

    bin/magento cache:flush

    chmod -R 777 var pub

After my web host ran the commands, he posted the output for me:

[root@sixteen public_html]# bin/magento cache:flush
Flushed cache types:
config
layout
block_html
collections
reflection
db_ddl
eav
customer_notification
full_page
config_integration
config_integration_api
translate
config_webservice
[root@sixteen public_html]#
[root@sixteen public_html]# chmod -R 777 var pub
[root@sixteen public_html]#

====================

The good news is that my website came back online. But there are some issues: the product images are magnified and overstretched, JavaScript and CSS files don't work. Website theme icons don't display in both the admin and front-end. In the admin panel, links are unclickable, because hovering a mouse cursor over any link shows that "#" is appended to it.

Please, do you have any idea how I can fix all those issues?

You've been so helpful from the very beginning, and you deserve all the kudos and much more. Thanks in advance for your continued support.

The static content deploy and cache flush should have resolved those issues. 

If you want to be confident you can clear more of the caches in advance of runnning that command again:

rm -rf pub/static/
rm -rf var/cache
rm -rf var/composer_home
rm -rf var/generation
rm -rf var/page_cache
rm -rf var/view_preprocessed

php bin/magento setup:static-content:deploy

Some further documentation on these commands: http://devdocs.magento.com/guides/v2.1/config-guide/cli/config-cli-subcommands-static-view.html

Other than that I'm at the edge of my ability of being able to help with this one.

Thanks. I've asked my host to run the commands.
