Installing Drupal

Hi Folks

I'm getting this on my home page immediately after installing Drupal 8:

Fatal error: Allowed memory size of 33554432 bytes exhausted (tried to allocate 72 bytes) in /home/johnmcc/public_html/podware.co.uk/vendor/doctrine/lexer/lib/Doctrine/Common/Lexer/AbstractLexer.php on line 265

There are no errors on installing - only the above when I go to my site

Any ideas what I need to do? I'm a novice on PHP but I've messed about with Drupal installation for a few years

Thanks
John

Hello everyone - I've been trying o install the Commerce Kickstart dist on a new, clean Ubuntu server. I installed the Ubuntu server with a LAMP config. I got everything to install and everything looks great until the very end and I receive this error:

Dear All,

You can try on http://ganeshaid.com/content/e-health-promotion-diabetes-type-2.html

After click Download button

Help please! I've tried to setup Drupal 8.0.1 on server many times, but i have these problems:
- Your MySQL server and PHP MySQL driver must support utf8mb4 character encoding. Make sure to use a database system that supports this (such as MySQL/MariaDB/Percona 5.5.3 and up), and that the utf8mb4 character set is compiled in. See the MySQL documentation for more information.

I initially posted this question on Stack Exchange but wasn't able to resolve the problem there.

I tried the following with Drupal 8.0.5 and with 8.0.6. I also tried deleting the website's root directory, dropping all database, and doing the following from scratch to ensure I can repeat this problem:
