500 Error when installing

[iMohamedSamir]

Hi, I am trying to install qlo by myself to try it.
I tried to install it locally on wsl:

ubuntu 20.04
php 7.2.34
mysql  Ver 14.14 Distrib 5.7.31
apache2

And I got localhost is currently unable to handle this request. HTTP ERROR 500
I thought there was something wrong with my wsl (fresh installation) so I installed every package mentioned in the dockerfile just to be sure, nothing worked.
so I grabbed wordpress version and proceeded to install it, and it have been installed just fine.
My last attempt was to upload qlo to my live server, created a subfolder inside a working project, and still when I access it, it gave me the same error

after soem digging and viewing apache2 error log i found the following:

So, As I thought, the problem was with php version, I used php7.2 As mentioned in docker's but when I downgraded to 7.0 it worked, anyway, I will keep testing

Hello @iMohamedSamir
As we checked the GitHub qloapps issue, and install it on EC2 instance with same configuration as you mention in the issue and it works fine.
We also check our dockerfile of qloapps and there are all the php packages written in the file.
When we check for the logs which are send by you in the issue then found may be you forgot to install the php package for XML, because all the errors which are metioned in issue are about XML file.
php-xml, php-simplexml - make sure these packages are present on your server.
Thanks and Regards

hi @ayushwebkul I have successfully installed qloapps on an ec2 instance. But on my localhost it returns with error: class "tools" not found. The php version on aws and on my local system are 7.2.34 the only difference being that some of the php.ini parameters on my system are more than required. The required php modules have also been installed along with the proper file permissions. 755 for folders and 666 for files. Any idea why this could be??
