Nothing relevant at the moment, Andrea, I’ll come back to you when the next updatee is made in the morning…my time, sorry, it’s a bit late here in Oz!

Yes, Andrea we are certainly editing the original posts, as they are the canonically important ones. But as a coding ignoramus I’m unclear as to how this would influence the set-up with the tags blog. We’re being redirected to a blog page that has nothing to do with the copy of the original post on the tags blog. How does this url collision come about, and does it simply result in a random redirection?

Presumably the “You have tried to edit a file that doesn’t exist..” message is also involved, or would that be a separate issue?

Unfortunately,the re-installation has not got rid of the weird redirects, as an update of a network blog post (which went through) resulted in a redirect to the edit screen of a “featured page” from the main blog home page (this has also happened on a previous occasion when a post was being updated, ending up at the edit screen of a different page featured on the home page).

I should note that the featured pages where I ended up are actual pages created on the main blog, and not pulled in from elsewhere. Hmmm.

Sorry, I should have mentioned I reinstalled the latest dev version of the SiteWideTags plugin.

Well, I deleted the plugin, couldn’t find any reference to sitewidetags in the DB (or anything that looked relevant) and now get on updating get an error with the phrase: ” You tried to edit a file which does not exist. Perhaps it was deleted?”. However, in distinction to others who have had the same error in the past, my post actually updates.

Obviously as I get an error message I don’t know whether the weird redirection problem has been solved as yet. More posts are due out later so I can check then (the site is live).

Thanks a lot, Ipestenu, I’ll give it a go.

Sounds hopeful! When you say “scrubbing it out of the DB” can you be more specific, i.e. what else do I need to do other than delete the plugin before re-installing?

Got it. Thanks for your help on this. I think I’ll take the more conservative approach and see how I go. If I split the approx. 40 blogs into 5 separate multisite installations, that should free up a lot of maintenance time while avoiding putting all my eggs in one basket (too chicken for that!).

Good grief, we have a minimum of one image on each post, uploaded to the media library, and a thousand or more posts. I’d assumed (stupidly) that in some mystic way the image links were rewritten – pretty dumb, now I come to think of it.

So the easiest way to solve this is to maintain my current uploads directory structure for legacy posts. Not elegant, but workable?

I may be slow, but why do you place copies in the new https://example.com/files/2010/ folder?

Thanks, Andrea, that’s very helpful. So the images embedded in a post would be OK, but any attachments would need to have their links amended?

Copy that. When it comes to ground-breaking, I wouldn’t feel happy unless I was at least one skill level above that notionally required, which rules this process out for me, I think.

So if I want to do it myself, I’d have to basically start from scratch, export all the blogs, install and specify one blog as lead, and then re-import the rest from the back-ups into the network? Presumably, it’s preferable to start with a clean database, so at least I can keep everything running until the last moment.

Has anyone else done this and can give me any heads-ups as to possible snafus?

Hi Andrea,

Sorry for delay in responding, I’m in Sydney, Australia.

I’d describe my ability to do that as basic, essentially limited to working via php admin at the “follow instructions” level. I am not a programmer and have only a rudimentary knowledge of coding. Sorry!

Tony

PS Of course, I could maybe pay someone more capable to do it, if this was a basically straightforward operation…

Hi Frederick,

I have now switched over to W3 TC for most of my blogs. You have provided a lot of information on settings in your answers to people on forums (you’re very active!) and this has been a big help to me in configuring my set-up. I had a couple of glitches where there was a large spike in load due to the swap file getting filled up, but it appears that this was not due to W3 TC but coincidental. At any rate, nobody at Pair (where I am hosted) could tie down an explanation.

I have not yet implemented APC but have already noticed substantial improvements. As soon as I have completed upgrading my blogs to 2.91 etc I will be trying out the op-code cache. I’m a little concerned about dedicating 128 MB to it as I only have 512 at the moment, and I am informed by Pair that Apache takes about 200 MB. Have you any suggestions as to modules that should be on my list for deactivating? I am not a programmer, so it may be that I could lose some of the more developer orientated modules. Any suggestions welcome.

I also haven’t set up the (in my case) on disk CDN yet, but as my theme is a little image heavy this may be a good idea.

Thank you for your stalwart work in putting this plug-in together, and supporting it so well.:-))

Hi Fred,

I was running hypercache, but deleted it when I switched to W3 Totalcache. Unfortunately the Google cache appears to have changed, and the first link doesn’t produce an error now. In fact, for the same search this thread comes up first!

I haven’t had any problems since, but I’ve disable HTML minification in W3 TC as you recommended.

I’m waiting for the 2.91 upgrade before rolling out the rest of the blog changes, but I have to say that W3 TC seems to be doing a great job speeding up my sites where implemented up to now. Looks like becoming the gold standard.

I’ve been getting an intermittent error to do with this on one of my blogs:
W3 Total Cache Error: Minify error: Unterminated String: "UA-146872-2

This results in a blank page with the error on it until I empty the caches. It hasn’t happened on any other one so far. I am using 2.9 and Joost’s latest. Unfortunately, the error was caught by Googlebot, so it’s currently enshrined at

• https://74.125.155.132/search?q=cache:6X7k3YkP5lcJ:www.travelsignposts.com/Germany/weather+W3+Total+Cache+Error:+Minify+error:+Unterminated+String&cd=2&hl=en&ct=clnk&gl=au

and a partial load:

As I have many blogs, it would be a bit of a pain to have to hand code analytics into them all, and I’d prefer to use the plugin. Have we got any more information on this?
