1. How to debug an apache virtual host configuration?

    Once again, I have a problem with my apache virtual host configuration. (The default configuration is used instead of my specific one).

    The problem is not really the misconfiguration but how to solve it.

    Does anyone have good advice to do resolve this kind of problem quickly?

    Some more pieces of information.

    The default conf file is this one:


    NameVirtualHost *
    <VirtualHost *>
            ServerAdmin webmaster@localhost
            DocumentRoot /var/www/
            <Directory />
                    Options FollowSymLinks
                    AllowOverride None
            <Directory /var/www/>
                    Options Indexes FollowSymLinks MultiViews
                    AllowOverride None
                    Order allow,deny
                    allow from all
            ScriptAlias /cgi-bin/ /usr/lib/cgi-bin/

  3. Changing PHP version with Valet and Homebrew (OSX)

    Recently, I updated the PHP on my machine to version 7.4 using homebrew for Mac OS only to then realise that one of my older projects that I still needed to maintain, made on version 7.2 would no longer work due to using depreciated PHP functions such as array_key_exists.

    The long term solution to this would be to update the project so it’s compatible with PHP version 7.4, but for the sake of time, and potential fixes that needed to go out immediately, I needed to be able to develop this project in the environment it’s running in. Fortunately, I use valet to develop all my PHP applications a tool I can only recommend for PHP developers. Valet allows you to develop PHP applications on your local machine with a much higher level of ease than I’ve found using other services such as dockers or XAMP/MAMP.

    Valet, with the use of homebrew, supports switching your system PHP version at will to any version installable via homebrew. So switching versions can be as simple as th

  6. magento 2 Please re-run Magento compile command

    Depending on your configuration it may also be unecessary. If you are in default or dev mode you do not need it.

    You just need it on production mode

    From command line and from your Magento root path:


    php bin/magento setup:di:compile

    P.S: After installing your module make sure you ran:

  7. Integrity constraint violation: 1062 Duplicate entry ‘4-Images’ for key – Magento 2

    Integrity constraint violation: 1062 Duplicate entry ‘4-Images’ for key ‘EAV_ATTRIBUTE_GROUP_ATTRIBUTE_SET_ID_ATTRIBUTE_GROUP_NAME’, query was: UPDATE `eav_attribute_group` SET `attribute_group_name` = ? WHERE (`attribute_group_id`=10)

    This particular error presented itself while upgrading from Magento 2.0.2 to Magento 2.1.x and stops the upgrade process. We’ve discovered the issue is related to old data from the previous Magento 1.9.x installation. In order to over come this error, you’ll need to delete a row from the database.

    Run the following MySQL query to find and delete the offending attribute.

    delete from eav_attribute_group WHERE attribute_group_name = 'Images';


    After that then you can attempt to run the upgrade command again and the issue should be resolved
