SUMMARY

The forum discussion addresses a widespread issue with LaTeX graphics not loading due to a server migration. Users experienced problems with LaTeX images not rendering, attributed to directory permissions on the new server. Warren confirmed that users can regenerate images by editing and saving affected posts. The issue has since been resolved, and LaTeX is functioning again, although some picture attachments remain missing.

PREREQUISITES
  • Understanding of LaTeX syntax and usage
  • Familiarity with server migration processes
  • Knowledge of directory permissions in web hosting
  • Basic skills in editing forum posts
NEXT STEPS
  • Research LaTeX troubleshooting techniques for web applications
  • Learn about server migration best practices
  • Explore directory permissions management in web hosting
  • Investigate methods for recovering lost image attachments in forums
USEFUL FOR

This discussion is beneficial for web developers, forum administrators, and users who rely on LaTeX for mathematical and scientific content in online platforms.

I can't see any LaTeX today. I only see little blue messages asking me to reload the page in a moment. Is it just me ?

No, it is everyone! whatever you are going to write with Latex right now, save it in a text file.
 
The site was moved from one sever to another today. I'm not entirely sure, but it's possible the latex images were not moved over properly. Let me go check...

It seems some (most?) of them were moved properly. I'm not entirely sure what's up right now... Please bear with me.

It appears to be a directory permissions problem. When it's solved, worst case, you'll have to hit "edit" and "save" on affected posts to regenerate the images in them. I don't have a login on the server right now, but will be able to fix it shortly. Sorry about this, folks!

Thanks chroot, I thought it was a setting on my machine...we will be patient.

Finally, \LaTeX is working again.

If you made posts which used TeX, and those posts were not parsed properly, go back and edit them. You don't have to actually change anything -- just hit the edit button and then the save button, and the images will be automatically updated.

Sorry again for the inconvenience!

- Warren
 
LaTex at last! Latex at last!

Thanks Greg and Warren!
 
Those few days without latex were a nightmare for me! I couldn't understand what was being posted in the homework and math forums.

I also realize that the picture attachments of the mentors that Greg has just made in the Member Photo Thread doesn't seem to exist. I think this problem has something to do with the LaTex problem. Even though LaTex works now, the pictures are still not there.

Hi Warren, there is no edit button for me to hit.

I just looked at a thread where I used LaTex in several posts and
it does not parse in any of the posts. It is a fairly recent thread
but not so recent that there's and edit button to use.

Have you any suggestions?

it is the thread with this post in it

Quite a lot of picture attachments are no longer valid. The chat room is down too.

The edit buttons have returned. We had a time limit on editing posts, but I have reset it to zero. Go ahead and edit those posts to have the latex images rendered.

When will this chat event be held? Will it be opened to everyone?
