Correction of error after updating WordPress to 5.7

In connection with the expansion of the assortment and the involvement of partners in the dropshipping system, we are looking for a specialist or team to create a modern online shoe store. An automated inventory management system is needed with the integration of partner Google Sheets. Main requirements: Responsive design for PCs, tablets, and smartphones. Product catalog with categories and filters (size, brand, color, price, etc.). Product page with photos, description, specifications, and size selection. Shopping cart and order processing. Integration of payment systems. Integration of delivery services. Customer personal account. Ability to add and edit products independently through the admin panel. SEO optimization of main pages. High website loading speed.Desired functionality: Wishlist. Automatic order status notifications. Integration of Google Analytics and Meta Pixel.Expectations from the performer: Examples of implemented online stores. Proposal regarding the platform (Shopify or another). Estimated cost and execution time. Further technical support after launch. Thus, the main feature of our store is that we work on a dropshipping basis and have several suppliers. It is critically important for us that the availability of products is synchronized between the suppliers' tables/files and the website, and that the stock is automatically updated according to current data. At the first stage, we need an online store with the following functionality: product catalog; product page; wishlist; cart; online payment; basic administration of products and orders. The user personal account is not a priority for now and can be implemented later. The most important part for us is the backend and the logic of working with products, stock, and data synchronization from suppliers. I would like to understand how you envision the implementation of such functionality in Shopify, OpenCart, or WordPress/WooCommerce, or other resources. Also, an important point: the website design is already almost ready, the frontend is in the form of an HTML mockup. Will you be able to work with the already prepared HTML version and integrate it into the chosen CMS, or will templates need to be redone? I would appreciate it if you could provide an approximate assessment: • Project execution time. • Implementation cost. • Which platform you would recommend for such a scenario and why. There will be more than 3 tables, these are the main ones as an example, generally similar in all templates; At the beginning, there will be up to 10, it is also important to have a process for adding new tables during operation; Do you consider Shopify, if not, then why?

Вітаю! Шановні фрілансери. Необхідно налаштувати передачу товарів з сайту на OpenCart на сайт Пром. Зі збереженням знижки на кількість. При цьому щоб мати можливість зробити націнку на товари, які передаються. Дякую. Прошу звертатися тільки тим, хто не "зникає". Працюю виключно через Сейф

It is necessary to implement a full cookie consent management mechanism (Cookie Consent) on the OpenCart (3 pcs) websites and configure Google Consent Mode v2. Requirements: install and configure a CMP (Cookie Management Platform) or another solution for managing user consents; implement a full Cookie Consent banner with options to accept, reject, and configure cookie categories; set up Google Consent Mode v2 through Google Tag Manager; ensure correct transmission of consent statuses to Google Analytics 4, Google Ads, and other marketing services; configure the operation of analytical and advertising tags so that they only trigger according to the user permissions obtained. Currently, the cookie banner is only informational and does not manage consents, nor does it transmit their status to Google services. A complete setup is required in accordance with the current GDPR and Google Consent Mode v2 requirements.

It is necessary to add 129 products. There is an export file with the products, however, the standard import does not fit, as it is necessary to create the catalog structure before uploading: categories, sections, and if necessary, subcategories. After that, perform the product import and check that all cards are correctly distributed among the categories. If you have experience with similar tasks, please send examples of your work, completion times, and costs.

WHAT NEEDS TO BE DONE The work is divided into blocks; you can take on everything or individual blocks: Block 1 — Speed Optimization (Mobile-First) The current PageSpeed score for the mobile version is 51/100.
