I recently installed “WP phpMyAdmin” plugin on another WordPress site.
It’s an excellent plugin and saves the tedious business of logging into the hosting server to access the database.
On the second attempt to run the plugin however I ran into a problem –
Session mismatch. Go back and click Enter phpMyAdmin button again. If you still experience issue, try to open a ticket at Support pages and provide some details.
After a fair bit of a search I came across a fix. Simply enter plugins/wp-phpmyadmin-extension/lib/phpMyAdmin_[followed by string of random characters] and delete the three files starting “_session_temp“
My next task is to write a small batch file to delete these without having to use FTP!
Programmes took an age to shut down, sometimes taking several minutes. It wasn’t confined to one programme. Any programme seemed to be affected. Also I would occasionally get a screen full of code on shut down [or boot, I can’t remember!] that flew past too quickly to read.
Then I started getting messages that my disk was full. This was worrying as I have a 1Tb HDD with windows/Linux dual boot. The Linux root partition was 50Gb and the home partition was 500Gb, both being big enough to avoid problems. Or so I thought. It was the root partition that was nearly full.
A quick check with Disk Usage Analyzer showed that the problem was log files. Tons of ’em. I deleted them [carefully].
Next I took a photo of the scrolling text. That at least allowed me to read some of it.
I selected a likely looking piece from one of the lines – “PCIe bus error severity=corrected” – and did a search on the web. I quickly found a solution.
Edit the file “/etc/default/grub” as Root user [making a backup of it first, of course].
I tried an update to the manager via the terminal. That didn’t work. I tried a few other suggestions that I discovered on the Web. Still no go. I decided the simplest solution was to reinstall 21.1 from the new ISO. I downloaded it and stuck it on a USB key.
Before booting into the key I went to backup my software selection. The Backup Tool didn’t work either. It just didn’t list any software. I resigned myself to a system reload. But before I started I thought I’d test Software Manager. That seemed to work so as a last resort (just for the devilment) I installed Gnome Update Manager. That worked, though it was a different program from the normal! It suggested a load of updates but I just selected Update Manager and Backup Tool. That worked.
In my Administration Menu I now had Software Updater and Software Manager. I tried the latter again.
It worked perfectly this time, as did Backup Tool. I applied all the updates.
