Diagnosis and recovery
Blank pages, 500/502/504 errors, failures after restarts and unavailable sections. Inspection of logs, configuration, permissions, connections and actual HTTP responses.
Self-hosted Bitrix24
Bitrix24 recovery and technical maintenance
I recover self-hosted Bitrix24 installations after server failures, problematic updates and module inconsistencies. I investigate PHP, database, file and client-side issues, then verify the portal’s affected workflows.
What I can help with
PHP and server environment
PHP configuration, extensions, OPcache and the Nginx/Apache chain. Preparation for PHP version changes with compatibility checks for the core, modules and custom code.
Modules and database
Investigation of inconsistent files and schema, incomplete updates and obsolete components. Comparison with the appropriate official packages and restoration of a consistent installation.
Web, desktop and mobile
Failures involving chats, messages, application assets and specific routes. Checks for shared server-side causes and issues specific to each client.
Custom code and integrations
Analysis and repair of third-party handlers, custom modules and templates. REST integrations, external data exchange and background operations within an agreed scope.
Planned maintenance
Upgrade and migration preparation, backups, recovery checks, performance and background processing. Changes made in controlled stages with verification points.
Relevant experience
Recovery after a system failure
A corporate portal required restoration of damaged PHP configuration and alignment of its PHP version, MySQL schema and deployed module files. Incompatible handlers were corrected and key sections checked.
Mobile messaging and desktop access
I investigated mobile startup failures and inconsistent immobile assets. Files were synchronised through the platform’s native mechanism, followed by checks of chats, messages and desktop routes.
Module-specific faults
Subsequent maintenance restored the sites and stores sections. An obsolete Sale module file conflicted with the current data model; the focused repair was verified using an authenticated account.

Bitrix24: corporate portal recovery
The PHP runtime, database schema, module files, desktop workflows and mobile messenger were recovered after a system-wide loss of synchronisation.

Assessment and scope
We define the process, source data and expected result. For an existing project, I review the affected code. We then agree scope, cost and milestones.
Development and verification
I implement the agreed workflows and check the result and its dependencies. Changes to live systems account for data integrity and neighbouring functionality.
Release and continued support
I prepare the deployment and rollback procedure and verify the result after release. I hand over the changes and we agree further support where needed.
What you receive
- An identified cause and an agreed recovery scope.
- Verification of affected sections and client workflows, not just running server processes.
- Backups, a change record and a rollback or next-stage procedure.
Before we start
Is this for cloud or self-hosted Bitrix24?
This service focuses on self-hosted installations with access to the server, files and database. REST integrations for the cloud edition can be assessed separately; server-level repairs do not apply to it.
Can a portal be repaired without a full upgrade?
Often a specific inconsistency can be corrected. The right approach depends on the files, database and installed versions. I establish the cause first, then we agree the smallest sufficient recovery scope.
What access is needed for diagnosis?
An error description, the time it appeared, recent changes and access to logs. Server diagnosis normally requires SSH and agreed permissions; we arrange access separately.
Can you guarantee an exact recovery time in advance?
Not before the cause and scope are known. After the initial investigation, I explain the options, dependencies and work sequence. Critical actions and any potential downtime are agreed before execution.
