I labeled the title generically because I believe the solution applies to many driver install problems.
I have a Dell Inspiron 580 which is about six years old. It originally ran Windows 7 before I upgraded to Windows 10. Windows update tried to install updated NVIDIA GeForce 310 video drivers but failed. I tried going to NVIDIA website and downloading/installing the drivers but it also failed. I also tried installing the drivers through device manager but it failed with error code 28.
I ended up fixing the problem by right-clicking on the NVIDIA downloaded driver and unblocking the file. That didn’t work (I think it was necessary), but I then ran the install in Windows 7 compatibility mode (right click on file, properties, compatibility mode tab) and it installed!
This solution surprised me.
I have never liked windows update installing drivers and wish there was a way to prevent it.
I was setting up WordPress so the admin area was secured by https:. I tried to login but would get a redirect to wp-admin/install.php. The often recommended:
1. Login to phpMyAdmin.
2. Select the database and click on ‘Structure’ tab.
3. Right under the list of table there is a “Check All” link. Click on it to select all tables.
4. From a “With selected:” drop-down menu right next to it, choose “Check table”.
1. Login to phpMyAdmin
2. Choose the affected database. If you only have one database, it should choose it by default so you don’t need to do anything.
3. In the main panel, you should see a list of your database tables. Check the boxes by the tables that need repair.
4. At the bottom of the window just below the list of tables, there is a drop down menu. Choose “Repair Table”
was tried but to no avail.
I checked the wp-config file and found out the table prefix did not match the database’s table prefix. I changed it and everything worked.
What happened was I recently ran a plug-in’s option to rename the table prefix from wp_ to a random one. I believe that wp-config was not changed. I’m not sure why it took so long to rear its ugly head because I have been in the admin area after said incident.
Smartlab Software had an interesting problem occur: a client was having MySQL connection problems only on Windows 8 or 8.1. XP, Vista, and Windows 7 were fine. The problem manifested itself by showing the HTML part of a dropdown box.
I verified that Windows 7 worked but in my case, Windows 8.1 also worked. One piece of the puzzle.
After poking around the Internet, a thought was the IP4 vs IP6 connection problem. This affected Windows 7 and 8 so it was unlikely.
The client booted up in safe mode and didn’t have a connection problem. In safe mode, the antivirus was disabled. It turns out the Windows 8.1 computers were brand new and came with a trial version of Kapersky antivirus. After uninstalling it and replacing it with another antivirus program, everything is back to normal.
I was working on a site that had PHP warnings turned off. The program I was working on showed a blank page. Creating and executing a new file, as shown below, solved the problem (which ended up being a parsing error). Indeed, a very nice php debugging technique.
I have been grappling with using SMTP in WordPress. For a while, it worked fine using an SMTP plug-in. The problem manifested itself by rejecting emails sent from a WordPress blog. In tracing the problem, debug told me I had a 550 error: recipient email address not found (which is not true). Finally, putting the same email address in “sender email” as in SMTP user name solved the problem.
I believe it is related to SPF (sender policy framework) record used by my host to prevent spamming. That is, the sending email address must be the same as the one that shows up in the ‘from’ email address. SPF prevents someone from putting a bogus email address in the ‘from’. Most major SMTP hosts and email companies use SPF (Google/gmail, yahoo, hotmail…).
I thought I knew how to refresh a browser – just hit F5 and you are done.
That is not quite true.
If you want to truly refresh a browser, the cache should be cleared out. The key sequences below will clear out the cache and refresh the screen.
Most of the sites Smartlab Software optimizes includes specifying an extended cache time for static files such as images and css. Imagine my surprise when this could not be done on GoDaddy shared hosting. I’m even more surprised because having a long cache time would reduce server load. It took a while to find this out. GoDaddy shared hosting does not support mod_expires.c (Linux) which means the webmaster cannot set an expiration date. I also could not turn off the Etag (as recommended by Yahoo YSlow). Hopefully, they will change in the future.
WordPress.org announced a critical update, 3.0.4. You can read about it here. The update fixes a bug in the WordPress HTML sanitation library which is used extensively. The vulnerability is through XSS cross scripting. We recommend updating your WordPress installation immediately.
I have probably deleted a lot of valuable emails.
Not because they are in the spam bucket, but because they look like spam. Like most business owners, I get tens to hundreds of emails a day. (Of course, having forty email accounts doesn’t help). Many of them are spam; many are not. The spam catcher does a decent job as it rarely gives a false positive on emails. But I digress.
In order to filter out more spam, I scan the ‘subject’ line and ‘from’ line of each email. If the subject line looks spammy, out it goes. If I do not recognize the ‘from’, out it goes…and therein lies the problem.
I have had many emails sent by legitimate companies both as initial emails and emails in response to one I sent. BUT, the ‘from’ name is unrecognizable. Most of the time, it is some person’s name. Period. Out it goes.
One innocuous example was I put a hold on a book at our local library. Several days later I received an email with someone’s name on the ‘from’ line who I didn’t recognize. I accidentally clicked on the message and it was from our library. I sent an email back to them explaining what happened and suggested they include the library name in the ‘from’ line. Next time I put a book on hold, the email notice had the library name included on the ‘from’ line.
Oh, if the email looks legitimate, I do check the ‘from’ email address. Knowing this can be spoofed, when I read the content, I check the links, if any. Sometimes the links will indicate one thing but link to an unknown, spam URL.
