Hi @Robin891229

Please turn on the dev mode then reload.
Then give us the screenshot of the error that is shown.
To enable the dev mode to go to your QloApps folder --- > config --> open define.inc.php file.
Then on line 29 change define('PS_MODE_DEV', false);
to define('PS_MODE_DEV', true);

@anteestenc i get the same error but i get back and first i check the connection to the database. when it says successful the error goes away.

Thank you

@tbalajadia

It looks the problem of your browser or server.
I request you to once clear the cache of your browser and the try to access back-office URL again.

I also request you to once check the admin folder (in your QloApps directory structure find the folder which name starts with admin) name in your directory structure.
If admin folder name has changed the try to access that folder from URL "localhost/hrms/admin_folder_name" .

I also request you to once visit https://www.ionos.com/digitalguide/hosting/technical-matters/err-connection-reset/ and try to resolve issues which may occur this issue on your system.

Please try once with the above solution.

If issue persists then please let us know.

@ecolr
while installation allow_url_fopen must be 1.
In the system compatibility we check ini_get('allow_url_fopen') and it is returning 0 on your server.
So you can first contact your host provider once regarding this.
If issue still persists then please create a ticket at https://webkul.uvdesk.com/en/customer/create-ticket/ and provide us with URL on which you are instatlling QloApps and FTP details in that ticket.

@OP

Please increase the value of memory_limit to 500 once on your server and try to upload the images again.

The issue was occurring on the last date of the month.
Replace the file. So that issue does not occur in future dates.

Many people will guide you using just command like: yum install php-soap, but you have to check your php version to install soap version for your website.
Hop it helpful to you!

Thank You. I will do that now.

To resolve the issue,

Please set 'allow_url_fopen = On' and 'allow_url_include = On' in php.ini

This issue generally arises because of the sql_mode variable value of your database.
We have resolved the issue. Please download a fresh QloApps and replace attached files in the below paths respectively.

After replacing the files install QloApps again.

@ab
It is the issue in MySQL version 5.7. So we recommend you to install lower MySql version like MySQL 5.5 or 5.6 on your server.

We have clearly mentioned in the QloApps installation guide about the required version of MySQL. https://prnt.sc/lywj11 .

Please visit https://qloapps.com/install-qloapps/ for installation guide.

currently, To install QloApps successfully, you have to install the compatible version of MySQL with QloApps. (MySQL 5.0+ and below 5.7 )

We really apologize for your inconvenience.

This issue is on our priority list. and definitely, It will be resolved in the near future upgradations.

Thanks

Hi,
Please ensure that the owner of the web server is the owner of the directory as well.
If they are not same then make them same and then try to install QloApps. And if still, you face any issue then please inform us.
