**Your software**

My Mautic version is: v4.1.1

My PHP version is: v7.4.27

My Database type and version is: 10.4.22-MariaDB

**Your problem**

I am getting `composer` errors when trying to install the @kuzmany [GitHub - mtcextendee/mautic-custom-tags-bundle: Custom tags for Mautic](https://github.com/mtcextendee/mautic-custom-tags-bundle) plugin

(The end goal is to to allow html code to be inserted into an email. It seems like the best scenario is to use the `{base64decode=customtextareafield}` feature of the mautic-custom-tags-bundle plugin.)

Steps I have tried to fix the problem:

- Using composer 2: `composer require kuzmany/mautic-custom-tags-bundle`

- Using composer 1: `composer require kuzmany/mautic-custom-tags-bundle`

# These errors are shown on CLI:

    - helios-ag/fm-elfinder-bundle is locked to version 9.3.2 and an update of this package was not requested.

You can also try re-running composer require with an explicit version constraint, e.g. "composer require kuzmany/mautic-custom-tags-bundle:*" to figure out if any version is installable, or "composer require kuzmany/mautic-custom-tags-bundle:^2.1" if you know which you need.

Installation failed, reverting ./composer.json and ./composer.lock to their original content.

## TRYING FROM WITHIN A DDEV INSTALLATION…

I’m not able to do the install using a `ddev` install of Mautic either. This time, I am getting different messages:

`composer require kuzmany/mautic-custom-tags-bundle -W`

```auto

Using version ^1.3 for kuzmany/mautic-custom-tags-bundle

./composer.json has been updated

Running composer update kuzmany/mautic-custom-tags-bundle --with-all-dependencies

Updating dependencies

Your requirements could not be resolved to an installable set of packages.

  Problem 1

    - Root composer.json requires kuzmany/mautic-custom-tags-bundle ^1.3 -> satisfiable by kuzmany/mautic-custom-tags-bundle[1.3.0, 1.3.1].

    - kuzmany/mautic-custom-tags-bundle[1.3.0, ..., 1.3.1] require mautic/core-lib ^4.0 -> satisfiable by mautic/core-lib[4.0.0-alpha1, ..., 4.x-dev] from composer repo (https://repo.packagist.org) but mautic/core-lib[3.2.x-dev] from path repo (app) has higher repository priority. The packages from the higher priority repository do not match your constraint and are therefore not installable. That repository is canonical so the lower priority repo's packages are not installable. See https://getcomposer.org/repoprio for details and assistance.

You can also try re-running composer require with an explicit version constraint, e.g. "composer require kuzmany/mautic-custom-tags-bundle:*" to figure out if any version is installable, or "composer require kuzmany/mautic-custom-tags-bundle:^2.1" if you know which you need.

Installation failed, reverting ./composer.json and ./composer.lock to their original content.

`composer update` did not help. ☹

I never got this working, but it was resolved by downloading the files from github and manually copying them to the /plugins/ folder.
