hi @brad-bell. I think there's still issues about PHP 7.1 because I have a trait with namespace Craft but my plugin is not reading the trait. You're suggestion to use PHP 7.0 for now resolved the issue.

I think you are onto something here! I am going to try using an earlier version of homestead with PHP 7.0 and see how that goes...cheers!

<p>Ok so this is an incredibly wierd one and I have no idea how to explain the problem in just one sentence so I just put the error message as the title.</p>

<p>So I am building a site with craft...in fact its basically complete. I was developing it in linux ubuntu but also using the vagrant homestead virtual machine to develop from so OS is kinda irrelevant. </p>

<p>Anyway...this is at work and they decided to be nice and get me a mac for work for christmas so I'm just basically trying to set up my working environment on the new computer.</p>

<p>So I set up homestead, pull everything from the git repositories, set up the databases and import everything...go to launch the site and I get the error message that is in the title and it highlights this line: <code>$value=unserialize($value);</code></p>

<p>ok...interesting...after some googling i read something and decided to try and go into my config file and turn off developer mode...</p>

<p>When I go to a normal page it gives me this error: <code>CDbCommand failed to execute the SQL statement: SQLSTATE[42000]: Syntax error or access violation: 1055 Expression #25 of SELECT list is not in GROUP BY clause and contains nonaggregated column 'db_name.structureelements.root' which is not functionally dependent on columns in GROUP BY clause; this is incompatible with sql_mode=only_full_group_by</code></p>

<p>I did some research into this and tried to edit my my.cnf file to modify the sql_mode parameter also with no luck although i think the line I was given was not correct for the version of mysql that I have...perhaps this is where the issue is?</p>

<p>...and when I try to log into the back end aka /panel it gives me this: </p>

<p>Your server doesn’t meet the following requirements to run Craft CMS:</p>

<p>Mcrypt is required.</p>

<p>Please talk to your host/IT department about upgrading your server.</p>

<p>Ok...fair enough...maybe I need this mcrypt thing...the thing is I think it is already installed? It is listed in my phpinfo(); I have gone through the steps to install it (and yes I have restarted nginx and php....and mysql and still nothing...)</p>

<p>I really have no idea what the problem here is...the only thing that i can think is that my vagrant environment is different to the one I had in linux as I downloaded it more recently but I have no idea what setting/software version number/whatever somewhere is different that might be causing this?</p>

<p>Please feel free to ask for more info as I really am not sure what I am looking for here...I know that the vagrant environment is working as well as normal php is running (as I was able to run the phpinfo(); function succesfully.</p>

<p>The vagrant box is running php 7.1</p>

Craft 2 (and the current latest version of the Yii framework - 1.1.17) are not yet compatible with PHP 7.1.

When the next Yii 1 release is out that addresses the framework compatibility issues, we'll get Craft 2 up and running on PHP 7.1.

Until then, you'll want to use PHP 7.0.x.
