Double opt-in dependencies
This plugin is an add-on to <a href="https://wordpress.org/plugins/contact-form-7/" rel="ugc">Contact Form 7</a> plugin by Takayuki Miyoshi. 
Functionality of this plugin also depend on installing and activating one of the plugins, which saves Contact Form 7 submissions to WordPress database. At the time, compatible plugins are:
<ul>

<li><a href="https://wordpress.org/plugins/contact-form-cfdb7/" rel="ugc">Contact Form 7 Database Addon – CFDB7</a> by Arshid</li>
</ul>
Note that BOTH Contact Form 7 and one of the listed above plugins are required for double opt-in functionality to work.

What is double opt-in and why use it:
Double opt-in is the safe way of receiving site visitor’s submitted input. Used with contact forms or online questionnaires or with user registration, it helps to reduce spam submissions. With GDPR laws, double opt-in is a strongly recommended way of getting user data. Because submitters have to confirm their identity from their email address, you can reduce risk of processing personal data without permission. Double – means here that user submitting the data has to give consent by checking checkbox option and additionally confirm their email-address. 
Do not forget to set acceptance field in your CF7 form if GDPR is in concern!
How Double opt-in form works:
When someone fills and submits a form with double opt-in functionality, the first CF7 email goes back to THEM. There is a confirmation link in that email, which the submitter has to click on or paste in their web browser. The link has two encrypted parameters: submission serial number and submitter email address. The page with “opt-in” slug validates the parameters with submission stored in WordPress database and initiates sending of final emails to recipient set in “All Opt-In Forms” settings. If validation fails or when submission has expired, no emails are sent. If there are no specified parameters in the URL, visitors of the “opt-in” page are redirected to “404” page.
Plugin translation
Double Opt-In can be easily translated. It is released with the translation to Polish language.

Cyrlitera converts Cyrillic and Georgian URLs and file names to Latin. It works for all post types, pages, and terms. It gives you options to define your own custom characters and enable automatic redirects.
<h3>How It Works</h3>
Transliteration is the process of converting characters from one writing system to another, such as converting Cyrillic symbols to Latin. Because most web software and URLs are designed around Latin characters, using Cyrillic or other non-Latin symbols in links or file names can lead to unreadable URLs, accessibility issues, and even broken links. Transliteration ensures your URLs and file names remain clean, readable, and compatible across all platforms.
Cyrlitera automatically replaces Cyrillic and Georgian characters with Latin equivalents to create clean and readable URLs for posts, categories, taxonomies, products, and custom post types. It also fixes incorrect file names by removing unsafe characters and transliterating them during upload, helping prevent 404 errors and broken media links.
<h3>Examples</h3>
Cyrillic URL before transliteration:
<pre><code>https://example.com/%D0%BF%D1%80%D0%B8%D0%B2%D0%B5%D1%82-%D0%BC%D0%B8%D1%80
</code></pre>
Same URL transliterated to Latin:
<pre><code>https://example.com/privet-mir
</code></pre>
Incorrect file names before transliteration:
<pre><code>%D0%BC%D0%BE%D0%B5_image_290.jpg
A+nice+picture.png
</code></pre>
Readable transliterated file names:
<pre><code>moe_image_290.jpg
a-nice-picture.png
</code></pre>
By using Latin-based file names and URLs, you avoid issues with encoding, broken links, and unreadable paths. This plugin performs the transliteration automatically each time a file is uploaded, ensuring your media library stays clean and consistent.
<h3>Features</h3>
<ul>
<li>Automatically transliterates all new permalinks for posts, pages, categories, tags, and custom post types.</li>
<li>Automatically transliterates all new attachment file names on upload, with an option to convert them to lowercase.</li>
<li>Creates automatic redirects from old URLs to new transliterated ones to prevent broken links.</li>
<li>Supports multiple alphabets, including Russian, Belarusian, Ukrainian, Bulgarian, and Georgian.</li>
<li>Fully customizable character mapping – define your own characters and their Latin substitutions to support any language.</li>
<li>Preserves original permalinks, keeping old URLs intact so nothing is lost during conversion.</li>
<li>Optional conversion of existing slugs, allowing you to transliterate existing URLs.</li>
<li>Rollback tool that lets you restore original URLs if needed.</li>
</ul>
