Hello! My name is Roman, from the Echocode team. Digital.
Most likely, after the PHP version change, some old functions or SQL queries in the website code started to work incorrectly (causing loops or so-called "heavy" queries that do not use indexes). Also, the MySQL server on the new VPS is probably running with default settings and is not optimized for the size of your database.
We have 8 years of experience in web development and administration of complex systems. We are ready to involve our Senior Backend Developer and system administrator to solve the task.
Message us privately! We will discuss server access, conduct initial diagnostics, and quickly restore stable operation to the website.

Hello.
Your problem seems similar to common complications currently faced with PrestaShop.
If the load increases for a certain period of time, it is likely due to aggressive bot scanning.
In this case, they generate all possible sorting options on the pages and cause such errors and high load.
It may also be a poorly implemented third-party module that needs optimization.
I have experience in solving all PrestaShop issues, from database settings to writing custom modules. In particular, I have a module for limiting the frequency of bot scanning.
Specific reasons can be discussed after access to the server and logs.

We already have a practically ready approach for diagnosing PrestaShop under load, which can be quickly adapted to your site and run the check; I am available to discuss.))
Preliminary estimate - 12,000 UAH and up to 3 days for diagnosing MySQL, PHP, modules, cache, logs 500, and basic troubleshooting of the identified cause.
If a heavy module or a problem in the data structure is found, I will provide a separate plan without unnecessary magic - because a cheap patch is often more expensive than proper diagnostics.
After stabilization, we can add AI log monitoring and notifications to catch such spikes before the site crashes.
At the start, we need access to the VPS, PrestaShop admin panel, MySQL, error logs, and preferably a backup or test environment.
Questions - what version of PrestaShop, PHP, and MySQL are currently being used, and is the slow query log enabled?
Another question - does the 500 error occur on specific pages, in the admin panel, during product imports, or randomly under traffic?

Good day. My name is Dmytro. I have experience in optimizing WordPress, WooCommerce, Laravel, and other web projects, as well as diagnosing issues with MySQL, VPS, and high server load.
From the description of the situation, it seems that the problem may be related to the database itself (slow SQL queries, lack of indexes, table growth) as well as the consequences of migrating the site to a VPS and changing the PHP, MySQL, or server environment versions.
I can conduct a full audit:
— analysis of MySQL load;
— search for slow queries;
— checking the database structure and indexes;
— auditing plugins and modules that create load;
— checking PHP, MySQL, and web server settings after migration;
— analyzing 500 error logs;
— optimizing caching and database performance.
After the audit, I will provide a clear report with the causes of the problem and carry out the necessary adjustments for stable site operation without constant increases in server resources.
I am ready to familiarize myself with the project details and conduct an initial diagnosis to assess the scope of work and timelines.

Good day. I can conduct a diagnosis of the website on PrestaShop and find the real cause of the load on MySQL and the 500 errors. I will check the operation of the database, slow SQL queries, modules, caching, PHP/MySQL settings after the migration to VPS, server logs, and the structure of the website itself to understand what exactly is consuming resources. After the analysis, I will not just provide general recommendations, but I will fix the identified problems: optimize queries, server settings, cache, problematic modules, or sections of code that create load. As a result, the website should operate more stably, without constant 500 errors and without unjustified growth in resource consumption each month.

Hello There is a small department where patients are admitted. It is necessary to develop a simple "database" where consumables, medications, and others can be entered, along with incoming and outgoing records, as well as assigning usage to a specific patient. Required functionality Directories Medications Consumables (manual entry option) Patients (ability to continuously add new ones and delete those who have been discharged) Employees (ability to modify)Movement Accounting A single table (movement log) where everything is registered Incoming and write-off Manual correction option When writing off, the nurse must select: date; patient; medication or material; quantity; her full name. The system automatically reduces the balance. When receiving, the head nurse must be able to enter: Delivery date; Medication/material; Remaining quantity; Source; Expiration dateAutomatic Functionality automatic balance calculation; minimum stock control; expiration date control; low stock warnings; protection against writing off more than is available; drop-down lists; data entry validation; conditional formatting.Reports It is necessary to implement automatic reports: current balances; usage over a period; usage by patient; usage by employee; history of movement of a specific medication.Preferred implementation on Google Sheets; We will fill in the databases ourselves. A template for work is needed. I don't know how much this costs, so let's start with $50, and you can suggest your options, preferably with experience.
