I started my plugins journey with this plugin, it showed me little bits of many techniques:
https://wordpress.org/plugins/wp-csv-to-database/ Author: Ruhul Amin

I would modify the plugin to do different tasks, each with its own button. One would be “add row to grid, it would have one field in its form, “keyword”. The code which handled the form submission would add that keyword to the table.

Another part of the plugin admin page is the grid. Probably a table of one column, each row containing a form displaying the phraseID and keyword and each language/multisite’s text, and a button for UPDATE and DELETE, this could be a table of one row and multiple columns. The DELETE button would delete all rows from the database with that phraseID. The UPDATE button would create a list of (a,b,c) entries and submit an SQL INSERT command, with a variation “on duplicate key update”.
It is extremely important that you use the “prepare” statement to construct the SQL statements using the fields submitted to it, without this you are vulnerable to SQL INJECTION attacks, an attacker can control your whole website.

Each submit action does the specified action, and reports upon the status of this action. Then it re renders the page, displaying the options and the new grid.

A different treatment would use AJAX.

You can only use one theme at a time.
What I would suggest is that you retain your theme and use the “child theme” mechanism to “borrow” the elements you need from your second theme.
Details on setting up a child theme here:
https://developer.wordpress.org/themes/advanced-topics/child-themes/
An alternative is to use:

Try:

.page-id-450 .site-header .main-header-bar {
background: rgba(0, 0, 0, 1.0);
}

First off don’t panic.

First you need to stop them getting back in.
Change the passwords on:
– hosting management login, probably cPanel
– all WordPress administrators
– the WordPress database user and password in your wp-config.php file

If you are on shared hosting, each website should have its own database, and use a different database user / password set.

Install one of the WordPress security plugins.

Another possibility is that while you have file edit permissions on the image as an interactive computer user, is that your apache webserver program does not have these permissions.

Firstly you should expect to be customizing your chosen theme as a child theme, this is an update safe method. Details here:
creating a child theme http://codex.wordpress.org/Child_Themes
If you find yourself choosing a child theme as a base then this may be relevant:

There are a bewildering range of themes to choose from, I think that “the look” is low in the criteria, again my opinion is that aspects such as viewing context be it Mobile / tablet / browser etc. Then there is integration as out of the box support and configuration with various plugins such as WooCommerce, this can save you a lot of work if your usage indicates. Finally it comes to the look, do you have a website colorscheme in mind, is it dark or light ? What about logo ? See how this relates to a theme’s header and footer, also sidebars etc. Yes you can customise any aspect of a theme but this has a longer reach than one would expect. For instance I inherited a website which had been changed to a dark background in the child theme, years later I find that filling in an alternate delivery address is impossible as the text did not contrast with the form background.

Building your own theme is a whole lot more work.

Suggest using one of the html / css validation websites to test your website pages, if you do have errors then various browsers on occasion behave differently. Like some browsers behave along the lines of “you made a mistake but I know what you mean anyway”, while others are bewildered.
Maybe ask in support forum for your theme.

I have built applications on WordPress that do this, so it certainly is possible.
You can write your code in two different ways:
– Create custom page templates in your theme, presumably a child theme.
– Write a plugin that registers shortcodes. Reference these shortcodes in your pages / posts and your code creates the displays.

One application is a genealogy wiki, subscribers input data about people in their family and connect to their relatives. Quite quickly the who ancestral village was covered, descendants around the world documented their family trees.
Another application scored contests, judges input scores and comments against the entrants, administrators supervised the progress, at the end participants viewed their results and reports.

There are also two different ways you can do the graphics (I have not done this very much):
– html5, runs on your server
– canvas: runs in javascript on the browser

Be aware that you will need considerable proficiency in several computer languages. My systems use a mixture of:
– PHP
– HTML and CSS
– SQL
– javascript including AJAX
