A CSRF Protector error typically indicates a session validation or security token issue in the iQ-WEB web application. In many cases, this can be resolved by clearing the browser cache and cookies and then reloading the page.
If the issue persists, the CSRF protection module can be disabled via the Windows Registry at:
Computer\HKEY_LOCAL_MACHINE\SOFTWARE\IMAGE Information Systems Ltd.\iQ-WEBX
by setting the value CSRF to false.
Important security note: Disabling CSRF protection is only recommended in secure internal network environments. It should never be used on internet-facing systems, as it reduces protection against cross-site request forgery attacks in web-based medical applications.

Incorrect or missing license information in the iQ-WEB licensing interface is often caused by a temporary failure or crash of the LicGen.exe process, which is responsible for generating and validating license data.
To resolve this issue, open Windows Task Manager, navigate to the “Details” tab, locate the LicGen.exe process, and terminate it. After restarting the process automatically or refreshing the Licensing page in the browser, the correct license information should be displayed again.
This component is part of the internal licensing system used to manage iQ-WEB modules within healthcare IT environments.

This error typically occurs when the iQ-WEBX WADO service license has expired. WADO (Web Access to DICOM Objects) is a core component used for retrieving and displaying medical images via web browser.
To resolve the issue, the WADO license must be renewed. Alternatively, the expired license file wado.lic can be removed from the following directory:
C:\Program Files\iQ-WEBX\PACS\php
After correcting the license state, the system should regain full study retrieval functionality in EasyWEB. WADO licensing is essential for web-based DICOM image streaming and browser-based radiology workflows.

Performance issues in iQ-WEB are often related to database configuration rather than the application itself. On heavily utilized systems, a common bottleneck is the MySQL configuration parameter innodb_buffer_pool_size, which is defined in the my.ini file (usually located under C:\ProgramData\MySQL\MySQL Server <version>).
By default, this value is often set to 128MB, which is insufficient for larger medical imaging environments. Increasing the innodb_buffer_pool_size to 4GB or higher (depending on available system RAM) can significantly improve database performance, query speed, and overall responsiveness of the iQ-WEB PACS web viewer. This optimization is especially important in high-volume radiology environments with frequent DICOM study retrieval.

Important: When editing my.ini, the value must be entered using MySQL’s shorthand suffix – for example innodb_buffer_pool_size=4G. Do not use “GB” (e.g. 4GB); MySQL will not recognize this format, and the setting may be silently ignored or prevent the service from starting.
