PHP MySQL CODING CHANGES TO JOBBOARD X2

I have 2 job boards written PHP MySQL In recruiter account a) at the moment I can only relist one job at a time, I want to be able to click multiple jobs on the relist option and upload all at once b) when i logged in as site admin rather than as a recruiter I want to have the option for the job ads to run for ever/eternity, but still have the option to switch them off to put them in expired jobs. On the candidate registration side CAndidates can currently register without filling in any of the forms/data, I want to make the parts marked with red stars obligatory so they must fill them in to complete registration. I believe it is a bug fix that some candidates can register without filling in pre requisits.

MySQL database needs to handle non-English characters

Experienced MySQL/WordPress developer needed to fix character encoding issues in a 391MB production database. Greek characters currently display as "???" due to charset/collation issue following DDoS attack some years ago. Tasks: analyze database config, convert tables and fields to proper UTF-8/utf8mb4 without data loss, correct connection settings, verify restored Greek text, and provide a safe migration plan for a staging environment. Expertise with backups, SQL conversions and WordPress charset nuances essential. (I'll shortly be setting up a WordPress staging site and it seems a suitable time to fix the database problem.)

Rewrite a Research Proposal for More Natural Academic Writing

I am looking for an experienced academic editor or dissertation writer to rewrite my DBA research proposal to improve its natural, human-written flow and academic style. The proposal has already been checked through Turnitin: * AI similarity is below 10%. * However, Turnitin still flags portions of the document for AI-generated writing. I am **not** looking for someone to simply paraphrase using AI tools. Instead, I need a skilled academic writer who can manually rewrite the content while preserving: * The original meaning and research objectives * Academic quality and logical flow * Citations and references (no changes unless required) * Professional DBA/doctoral-level writing style ### Scope of Work * Rewrite a few research proposal section by section. * Improve sentence structure, vocabulary, and transitions so the writing reads naturally. * Maintain all arguments, methodology, hypotheses, and research intent. * Ensure consistency in tone and formatting. * Return the document with Track Changes (preferred) or provide a clean final version. ### Requirements * Strong experience with academic writing, dissertations, or doctoral research. * Excellent English writing skills. * Familiarity with Turnitin reports and academic writing standards. * Ability to deliver high-quality, original writing without altering the research content. The proposal is approximately 36 pages titles, references, images and the content. But updates are very less. Please share: * Examples of similar dissertation or research proposal editing work. * Your estimated turnaround time. * Your fixed price for the project. This project may lead to additional work, including editing future dissertation chapters, if the quality is excellent.

MS SQL EXPERT NEEDED (USA BASED ONLY)

As an expert, you must be residing in the USA, be able to provide a W9 tax form as a consultant, and sign an NDA. The project involves analyzing a complex MS SQL database with over 1500 tables in order to dump and convert the raw data tables into MySQL. The backup is nearly 15GB of data. The schema is based on Enspire ERP and requires the ability to identify which tables are joined in order to output relevant archive data. You will work together to provide samples of what data fields are identified and narrow down only those which are required. Many system fields are likely and not needed, so it will be a process of working together to adequately arrive at a curated MySQL database. Migration of resulting data will be part of the process onto a Linux cloud server with MySQL installed. Project will be awarded based on best overall estimated total hours to complete.

Fix MariaDB issue on Plesk server

Yesterday I restarted my plesk server using the Plesk interface. Straight after this I was getting the following error when I visited my server: Server Error 500 Plesk\Exception\Database DB query failed: (2002) SQLSTATE[HY000] [2002] Connection refused Type Plesk\Exception\Database Message DB query failed: (2002) SQLSTATE[HY000] [2002] Connection refused File Mysql.php Line 79 I could only access the server and my sites when I used this command (sudo -u mysql mariadbd --skip-grant-tables --console). when I closed the command prompt the server and sites stopped working. I spent ages using AI to try to fix the issue. It gave me a command and now I can access my server. however my databases are shown in plesk, but when I go into them into phpMyAdmin, there are no databases and there is an error at the bottom saying: The phpMyAdmin configuration storage is not completely configured, some extended features have been deactivated. Find out why. Or alternatively go to 'Operations' tab of any database to set it up there. Because phpMyAdmin is showing no databases or tables, my websites are still not working. Also for some reason webmail doesn't work for all of my sites. I need my websites and emails back up and running
