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.
If the issue persists the please create a ticket at https://webkul.uvdesk.com with your Admin login details and FTP credentials.

We have also already developed CC Avenue payment gateway compatible with QloApps.
If you want it then you can purchase it from https://store.webkul.com/CCAvenue-Payment-Gateway-for-Qloapps.html

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

Which the isussues: In the PHP configuration set upload_max_filesize to minimum 16M"
====change two file size one three location:========

upload_max_filesize = 40M post_max_size = 40M
#/etc/php.ini

=========Fix SOAP extension is not loaded==========
#yum install php56w-soap
php56w-soap.x86_64 0:5.6.40-1.w7
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

Also please make sure that there issue no issue in your internet connection because many times this error arises due to a connection problem.

Also, make sure that your server configuration is compatible with QloApps. You can find the required configuration in this guide.

And we are working on your ticket to resolve the issue.
Please expect our response on this issue on ticket only.

Thanks

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.

hotelcommerce/classes/db/DbPDO.php hotelcommerce/install/data/db_structure.sql

After replacing the files install QloApps again.
Hope it will be installed successfully.

@akr

Thank you!
Since I also asked Synology for help, the result was that the timeout value was too low, Synology also suggested to change it to 300, and I set it to 600 in order to reduce the trouble. So it has been installed normally.

In addition, there is another problem, that is, in the translation part of "Localization", the input translation cannot be stored normally...
I have set max_input_vars to 60000, but the translation still cannot be saved as a result. What is the recommended upper limit value of max_input_vars? The translated language is "Traditional Chinese".

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.

@Faiz Hi again, so problem is solved and installation was succesfull
