Drupal 7.x

Dear community

I need some help understading why my website is slow (TTFB), I have installed devel module and I can see that for some reason the semaphore table takes a lot of time deleting/inserting records. As I understand this is part of Drupal core but why is it that slow ? 

What can I do to sort this out ?

I'm updating a site from Drupal 7.12 to Drupal 7.69. I'm using MAMP which is running version 7.3.8.

I'm getting these two errors, and I've searched for patches or fixed updated versions, but no luck.

I'd like to get that on the Rules form.
I have an 'administration office' user who in a page view checks with a checkbox the issued/not issued invoices.
Sometimes the non-issue of an invoice can be due to many reasons, and may even take several months.

I would like that when the 'administration office' user logs in, he receives a message 'hey, there are still some invoices not issued! Check them".

I tried "Drupal is initializing" and "User has logged in", but from that point on I can't check the content types and their respective fields.

I have been developing in Drupal for quite some time and I have a fair bit of skill in programming.  But I have run into this problem numerous times when trying to help others to begin using Drupal.  The Drupal core is installed, and a default, site is created.  Then a theme, free or purchased, is downloaded and added to the system.  It looks great!  Awesome!  Are we done?  No, now we have to figure out how to make that generic "Lorem ipsum" site take our specific content.  Low and behold, all that flashy, beautiful imagery and fake Latin content is hard coded right into the page.tpl.php te

In a company page i have two blocks
The first block display the company products, and the second one its employees.
The second block has a paged display. When i browse the second block, first block get no result.

Both blocks are show in 'company/*' path, but browsing the second one the path change in 'company/the-company?page=1

It isn't essential, but a little bit annoying.

Is there a way to solve this issue?

Many thanks to who could help me

Hi, I am looking to create a view showing all taxonomy terms of a particular vocabulary in a row. I need to see which terms are translated into which language and if some are missing it would be easy to see where to add the terms.

I am only using three languages currently. I have been able to create a view for all terms of different vocabulary, but I am missing the trick to addd columns showing me the related terms of the other languages.
